Nearing a decade ago I released this web (demoscene) demo  called "Awakening" as a tribute to my oldskool demoscene PC group Darkzone. 

All models are either generated or modified by code realtime,  and all movement done with code, synced to music manually by hand.

At the time I was heavily into using Macromedia Director (now Adobe Director) and Shockwave 3D. This is a bit dated browser plugin technology now, BUT it is still developing, and there are current rumors Director 12 might be able to generate content/games to run on iPad2 and iOS, rumors! but exciting!?

Check out www.zebraimaging.com they have realtime holographic displays, interesting tech!
