Hello,
Perhaps this is the first example of the use of Bullet in a Flash game. I converted it using Adobe Alchemy:

Great physics engine, keep up the good work.
PS If you press F12 in game to access the console, and enter "var showphysics 1" (without quotes) you should see a familiar looking debug-draw!
EDIT: above URL seems broken. The game is also online here: http://www.pbmcube.com/pbm3/games/shortrail-pool (or google for shortrail pool)
