It's sort of good, but it:
a) has no true interactivity
b) is strikingly similar to a certain popular screensaver
c) devolves quickly into a mess of swirling white dots (albeit still very pretty IMHO)
Fix those, and you'll get maybe... a 7-8, maybe 9?
For now though, you get 4/10 2/5.
I posted this so anyone can study the code, see how this simple 3D engine works (pure math), and how the bitmapData stuff works.
Basically, its a .swf for developers, not players.
you get a five cuz i already have this screensaver
...but it's just a demo. The only interaction you have with it is the angle of view. It's something to work with, modify, etc. I suppose.
