My largest project since March of
'92 has been for First Advantage
Corporation, working on a system to enable manual fulfillment of
background screening tasks.
Prior to that, I worked for Pioneer Digital Technologies, on an interactive television administration system for cable operators. Screenshots are here.
Blaster! -- an Asteroids-type game for the Mac. I wrote this in one week using C++ and the OpenGL library. Download it here. (Beware: I wrote this several years ago, and your machine may be too fast for it.)
