Rendering stereoscopic's not that hard. It's just rendering the same view from two different cameras spaced eye-distance apart roughly where you expect the viewers head to be. ie, your view system geometry has to match real life as much as possible.
Yes it would be very cool to do a demo like that

I love all this maths stuff. I've been working on a 3d engine (OpenGL for rendering to save acres of code) that uses just 3d primitives to generate all the objects. But it's still difficult making great models out of sticks, balls, cones, cubes and stretched/bent/combined versions of the above.
