I made a bunch of iOS apps, 2010-2016.

All broken forever, but cool at the time.
ClimberMan was a simple game that I used as a starter project for my students' games.
GeoMelee was a project I made in collaboration with some students: a GPS-enabled StarCraft clone.
JunkSpace was an art App, made with Lynn Cazabon, a GPS-enabled AR that shows orbiting objects as they pass overhead.
It showed, just, everywhere, for what that's worth: bah.
Medsitations was a game that looks at the links between meditation and in-game concentration. Pretty.
NAS Dome Explorer was a collaboration with UMBC's IRC, an AR app that makes architecture more interactive.
Starry Eye: a Star Castle clone, but more trippy.
Sight-reading tutor: tutorial app for learning to sight-read clef notation.
Ukieshaker: a ukulele simulator that uses the accelerometer to control strumming.
The audio units code running in iOS 3 was such a stunt.
Driver John: a DirectX/OpenGL Windows game I made in 2001.
Indie game development, about two years too early.
the PAG: A GAP, implemented in Half-Life, in 1999. Gabe Newell bought in!
That's right: we pitched to Gabe, and he gave us money, and then the dot-com bubbled!
