As I posted earlier, the video tracker is done (est cost with cheap camera:
$600 or so).  Now I'm thinking of ways to show it off, without spending
weeks writing software.  Point tracking is very trivial, object tracking
almost.  BUT: how about a simple VR videogame?

OK, I know it's been done, but I don't want anything that will take more than
a weekend of programming.  Two ideas come to mind: Handball and VR World.

Handball:  The ball moves with gravity (maybe a few simple barriers, etc)
and contact with the silhouette on the screen gives it a new motion.
Trivial (in fast C on a 386) to get 10 fps, and 2 players is easy too
(but not telling them apart...) Of course, everything's in 2D for now.

VR World:  A simple set of objects that can be lifted, placed on shelves,
and simple controls that can be manipulated.  Hands would not be discriminated
from other body parts for now.

Any (very simple) enhancements?  I only will have a couple of days to do this
demo, so keep 'em easy.  But all suggestions are welcome...
