Author's note - After some damn good ideas in Part 3 for how to handle this, I've decided on this format unless anyone really complains. As there's a LOT of plot stuff that has nothing whatsoever to do with tickling, I'll post alternate parts (tickling, non-tickling etc) in whatever length they happen to come in at. Sorry to all those of you that ain't interested in the plot stuff, I'll try to make up for it once I'm done with this story (should be about christmas 2004 at this rate...)
Part 4
Eventually Fiona cried herself out and lay silent against Steve’s shoulder. Gently he lifted her up slightly and eased her back against the sofa.
“Now, what’s wrong, and does it have anything to do with why you want to hurt me?” he asked.
She hesitated before replying, suddenly aware of just how silly she was going to sound. “You, you programmed that, that thing into the sim and it wasn’t what I wanted, it was too much I couldn’t take it, just too much and…”
“Shhh, slow down lass, one sentence at a time and remember to breathe, it’ll help.” Steve said, doing his best to keep her calm. “About the only bit of that I caught was about something being programmed you didn’t want?”
“Yes, that man, what he did to me, to her…it was…” Fiona trailed off, her mind threatening to shut down as the events of the previous night tried to rush back.
“Ummm, I know this is going to sound ridiculous, but I never put anyone, or anything in that sim other than what you asked for. Just you and Nicole, that was it.” he said, confusion clear on his face.
Fiona felt her anger spark again, grabbed the memory stick from her jeans and thrust it at him. “Here, take a look for yourself if you don’t believe me,” she snapped. Steve reached out and took the recording, turning it between his fingers with an action so well practiced it was practically reflex.
“Okay, give me a few minutes to look at this, feel free to make yourself at home.” Steve said, heading for the door.
Fiona heard the door to what she assumed was the bedroom shut and the faint whine of a computer coming on-line. She found herself restless and started looking around the room. It was a pretty normal living room by most standards, a large plasma screen dominating one wall, flat speakers hung next to it, with a matching set on the back wall. A large bay window gave a view of the small, neat garden and bookshelves and cupboards dominated the rest of the wall space.
She walked over to the shelves and started flicking through the movies and books noticing they were stored in a seemingly random order. The movies where what she’d have expected for the most part, sci-fi and action flicks, with the occasional deeper, thought provoking film mixed in, although she realised that, somewhat to her surprise, they were all normal films, not VR titles. She would have expected it to be the other way round, considering what their owner did for a living.
The books were more of a puzzle, there was seemingly no pattern at all to them, and they covered a vast variety of subjects, from military vehicles and combat tactics, through music and art, to the sciences of physics, mathematics and what seemed like every computer discipline under the sun. All of them were well used, and had that familiar half-worn look that suggested they were used as reference books for the majority of their life.
Her eye was drawn to a small set of shelves at the back of the room. Unlike all the others this one had a glass door, though there was no lock to prevent curious visitors prying into its contents. Inside there was an eclectic collection of objects, several books lay on the bottom shelf, the middle two were taken up by a couple of photographs in frames and the top held what looked, for all the world, like a sword.
Her curiosity got the better of her and she opened the cabinet and carefully removed the sword from it’s stand. It was what she thought of as a Samurai sword, long, thin and gently curved, the handle bone white and a small round guard between the handle and the blade. It was surprisingly light and the balance was amazing, almost as if it was simply an extension of her own arm. She pulled the sheath a little way off the blade and saw this was no replica, the edge gleamed as if it could cut through time itself, in fact she half expected it to glow. Moving as quickly as she dared she put the sword back in its place and looked closer at the other items.
The photographs were odd, one of a young woman in her early or mid twenties, dark red hair framing a pretty face that was, in the timeless moment captured by the camera, locked in an expression of pure joy. The other picture was of a sea, perfectly flat without a ripple or wave to be seen. The sky was pitch black and from maybe two thirds of the way from the left edge of the picture a perfectly white bolt of lightning connected the water and the heavens, like the finger of god himself.
She moved her attention to the books and noticed immediately that they all had one thing in common, the author. All were written by a Steve Franklin, she presumed the same Steve that was currently working in the next room. Two were fiction books, written about ten years ago, one a sci-fi story with a picture of spaceships dog fighting in an asteroid field on the front cover, the other was called Bloodhounds, the title written in red on a black background that had been designed to give the impression of fabric caught in a breeze.
The remaining books were more recent, all written within the last five years and dealing with various aspects of VR. A quick check of the titles showed they covered pretty much everything, from security and military applications, all the way through to AI design and graphic modelling. She flicked through a couple, but the concepts involved were way beyond her knowledge and she slid them back into place. Stepping back she shut the door and turned round, before jumping almost out of her skin as she saw Steve standing at the door, watching her intently.
“How long have you been there?” she demanded, angry and embarrassed in equal measure.
“Not long, I just wanted to make sure you saw everything you wanted to before disturbing you. I think you need to see this.” He replied, his usual good humour replaced with an expression of worry. Fiona followed him through into his bedroom, and stopped dead as stepped through the door.
There was a bed and wardrobe at the back of the room, but every other inch of space was dominated by computer equipment. One wall held racks of components and systems in various stages of repair, the other what looked like a cluster of working kit that put the systems she’d seen in work to shame. A desk dominated the remaining wall, flat screen monitors mounted to the wall behind it, four keyboards scattered on the wood in front of them. It looked like a mad scientists wet dream, like you could create any doomsday device you wanted without ever leaving the room, and it was a formidable sight.
Steve was already at work, calling up a set of diagrams on one monitor and a still shot of the mysterious man she’d encountered in her program in another. “Umm, just before I get going on this, how much do you know about VR, how it works I mean?” he asked.
“Not a lot, I kind of know the basics, how the suits work, the usual safety stuff but that’s about it.” Fiona replied, still slightly shocked at the contents of the room.
“Then grab a seat and I’ll try to explain this as best I can. All objects in a VR world have three main parts, doesn’t matter if it’s a character or a plank of wood everything’s built the same way.” As he talked Steve’s hands flew over the keyboard, creating a basic white outline of a person on the screen.
“First there’s appearance, that’s the easiest part to get right, especially if you’ve already got a set of reference images. Provided there’s a complete image of the character from all angles the computer can put together a pretty convincing representation.” On screen the outline became solid, filled in with the image of the man she’d seen. A few more key presses and the image seemed to fade out, becoming almost transparent as she looked at it.
“Under that there’s the physical attributes, in this case things like bone and muscle structure and their basic physical properties, how they interact with each other, their density and composition, that sort of thing. These days that’s pretty simple, at least for standard images like people, as there’s a huge library of examples to borrow from.” The image changed, adding the internal structure of the man over his physical appearance, then that too faded.
“And finally we have the real magic, the personality matrix. This is what governs how that character or object will behave, how it will react to other objects in the world, including real people. That’s what takes the time to build, and what separates the good from the bad when it comes to programmers. With me so far?”
“I think so, yes. Though I find it a bit hard to believe that a rock has personality.”
“Believe it, there have been some really weird occasions when someone’s loaded the wrong personality into the wrong object and a bunch of trees tried to do the can-can.” Steve grinned as Fiona burst into giggles next to him, he wasn’t at all convinced she was over what had happened so quickly, especially after reviewing the recording, but at least he could take her mind off it.
“Now when we put it into VR what we end up with is something like this…” he said, manipulating the image, turning it into a simple 3D outline on the screen with three layers of colour across it. “The red layer is the appearance, the blue the physical structure and the green the personality matrix.” He said, pointing out the detail as he did. The red band was a thin layer around the outline of the image, the blue a thicker one underneath it. The green was a tight sphere in the middle of the figure, with two thin white lines reaching out to connect it to the blue layer.
“What’s the white layer?” Fiona asked, her curiosity peeked.
“The white lines show the input/output pathways between the personality and the rest of the object. Think of them as the equivalent of nerves in your own body, carrying data about the outside world, in this case the VR scenario, to the mind and passing the commands back out to act on that stimulus. Of course the mind in this case is the personality matrix, and it’s really only approximating the actions of a human mind, but the idea’s much the same.”
“Hang on, if they’re nerves why are there only two of them, I mean, there’s thousands of them in our bodies, right?”
“Ah, there you hit on the real problem with VR. You see, running these scenarios takes a huge amount of processing power, even generating the graphics on a flat screen like these would have been beyond most computers ten years ago. Now we’ve got a lot more power to play with, but at the end of the day it’s still limited in what it can do. See the more data you feed to a decision making process, which is effectively what the personality matrix is, the more processing power you need to process it. In fact it’s exponential, double the data and you’ve got to quadruple the power.”
Steve paused for a moment before continuing. “Basically, all computer design is a trade off between what you want and what you can get. In VR the compromise was in creating believable characters who seemed to genuinely interact with the user and realistic environments to fool the brain into believing it’s actually in a different place than it was a few seconds ago. This was the solution they came up with, and it works pretty well. There’s enough of a data pathway there for an object to pull in as much information as you do through any two of your senses. The trick is it’s a switched system.”
“Okay, now you lost me.”
“Think of it as a two way, one lane road okay? Traffic can move along it in both directions, but only one vehicle at a time. If you’ve got two cars wanting to use it at one time in different directions one of them has to wait until the other has gone through. It lets an object respond quickly enough to fool the user into believing their acting spontaneously, and get enough data to make sure that response is appropriate, without needing ridiculous levels of processing power to do the job.”
“Now, let’s break down your mystery man shall we?” He hit a few keys and the still shot of the man blurred, turning into the same basic 3D shape as shown on the other monitor and Fiona gasped. The red and blue layers were the same, though slightly thicker on this version. The green layer was almost five times as large as that on the original display, almost touching the inner edge of the blue band. But that wasn’t what had caught her attention, overlaid across all this was a mass of white lines, like lightning frozen inside a storm cloud, more connections than she could possible count.
“Now that, ” Steve said, voice low and hushed “is not your standard VR character.”
“What is it?” She asked, her own voice wavering as she tried to understand what she was seeing.
“Honest answer? I don’t know. It’s not human, we don’t show up the same way in VR, at least not to the system itself. It could be a program, but there’s two problems with that. One, the time and effort needed to create that size personality matrix would be almost inconceivable. Two, there’s no computer on earth that could process that amount of data in real time. Now either of those problems pretty much rules out the option of it being a program, which doesn’t leave a whole hell of a lot of options.”
“So what do we do now? I mean, this…whatever it is, came into my sim, my system and tortured me half to death. I’m not exactly in love with the idea of meeting it again, you know?”
“Okay, I think the first thing you’re going to do is to get some proper rest, you look exhausted lass. I’m going to make a few calls, see what I can find out about your system, who could have accessed it, how they could have got in, that sort of thing. Then tonight we’re going to make a call to the market and see what we can find.”
“The market? What’s that?”
“Hmm? Oh, it’s the kind of simple, doom-ridden name the geeks of today like to use to give their activities that little hint of danger. Don’t worry about it, it’s just a meeting place for the less reputable members of the computing world, pretty much the most dangerous thing there is exposing that many geeks to someone as beautiful as you at the same time. Hell, it might help cut down the computer crime rate if some of them realise there’s a life outside of VR.”
Fiona smiled and half turned to hide her blush. The comment had been made off-hand, but she had to admit, hearing this man refer to her as beautiful was not entirely a bad thing. Steve showed her to the guest bedroom and made sure she knew where everything was before leaving her alone. She looked around the non-descript room, surprised at the contrast between this and Steve’s bedroom. She flushed again as she found her thoughts lingering once more on the bed part of that sentence and laid herself down on the single bed. She was asleep almost before her head hit the pillow.

Eventually Fiona cried herself out and lay silent against Steve’s shoulder. Gently he lifted her up slightly and eased her back against the sofa.
“Now, what’s wrong, and does it have anything to do with why you want to hurt me?” he asked.

“Yes, that man, what he did to me, to her…it was…” Fiona trailed off, her mind threatening to shut down as the events of the previous night tried to rush back.
