[SP] Prey
An introduction to Surface Translation Matrices. (Prey style wall-walking gravity panels).
This is a little map I've been working on for a while now, based on the wall walking principle. I've tested the hell out of it and it should be pretty stable, but it's really pushing what's actually possible with only source IO and VScript. So you'll have to forgive me if it crashes or stops responding. (In such cases, just type 'kill' into the console and you'll be taken to the last safe spot).
It doesn't use gels like Omnicoder's system but works fairly similarly (if he's not busy changing it again).
Anyhoo, cheers OC for the clue that sparked the eureka moment 
Why did you have to release this now? :d
I was waiting to play this on release but now I'm sitting here watching a sunset.
My father went and got an ipad so I can surf internet with this but playing portal won't work.
Just decided to say hey and I will be sure to play this right after I get home.

Lol, I can't feel sorry for you sitting in a beach house by a lake, holding an iPad Shakky...
I can honestly, and without shame, say that I was completely confused for about 90% of this. 
It was certainly interesting and maybe tomorrow when the confusion wears off I'll be able to say that it was fun. It was so mindbending, my body feels like its floating somewhere near the ceiling. Those are all meant to be taken as compliments, by the way.
I had two problems: the invisible death fizzlers and I would sometimes lose a portal if I transitioned too quickly from one orientation to the other. I'm not sure why you have to rebuild the portals after those transitions, but I assume you have a good reason. Also, I never found a use for the regular cube.
Well, done, sir.
First of all this house is by a river not a lake and the internet connection super slow.
To be honest I'm really happy to be here but I wish I had Portal 2 here with me.

@RogerL
Heh, cheers - looks like it had the desired effect! Took a while getting used to using hammer upside down too >.<
A few people have raised concerns about the deathfizzlers, so I went head and switched them for LP's. They're not as opaque as I thought, so it fits pretty perfectly
Edit:
Ty for pointing out the test cube, I'd forgotten about him!
@Shakky
Build yourself a companion cube out of mud and sun bake it tomorrow. You will be graded on 3 main criteria:
-Demonstration of skill and good craftmanship.
-Creativity and Ingenuity
-Effort, hard work and the overall success of the project.
Well I haven't played it all the way through, but this happened to me:
I got stuck inside one of those "wallwalker" thingys, I don't know what to call them.
I might check this out and complete the entire map, but I have to sleep now. Swedish holiday tomorrow xD
Awww balls.. thought I'd fixed all that... what were you doing at the time?
It's a pretty pic though ^^
The new fizzlers are much better. I got stuck just like Logic did. It was just before the fizzler entrance to the second cube, though it was the first time it had happened to me.
It also reminded me of something I forgot to mention in my last post. I was yo-yoing one of the cubes (in the room just outside the final room) to see if I could get it into the room where you get the second cube (this is before I found the correct way). But every time I transitioned to a new angle, the cube just stopped its yo-yo. Odd behavior, I thought.
