Most of my work was on implementing the actual calculations for relativistic effects.
It was coded in Unity Game engine in C# mostly. The hard calculations are actually all calculated in a shader written in Cg (mostly just C) so they're on the graphics card.
Also why is it that you can't see the Lorentz transformations until the final orb? I'd have thought that they'd be apparent somehow -- is it somehow cancelled out by visual effects?
There were also a few other documents I had but they don't appear to be hosted online anywhere.
The Lorentz transformations are not as apparent as the visual effects, they're not canceled out though. You can actually see them, try speeding up and slowing down when you have >50 orbs. You'll see a warped view and such :)
I also would have expected to see some sort of length contraction evident in things like the fence post spacing, but I never noticed any.
The end has all the crazy distortions that make it fun.
