Jason Mauer (
blogless boy wonder www.jasonmauer.com ) has created an amusing and educational Managed DirectX app that demonstrates
collision detection and rigid-body dynamics. It's a simple demonstration that just uses billiard balls. However, the beauty is that it covers several complex subjects in a relatively simple manner. Be sure to download it and, if you'll pardon the pun...have a ball!
updated: Jason pointed out his blog location, which could easily be found doing a simple search. That's what I get for posting at almost 2 in the morning

2nd update: Jason asked me to point to the
www.dxdot.net website for the download link. Are you happy now, Jason?
