QuMa - The first ever Windows based editor for Quake maps. Wow, I had essentially
what you'd call a blog back in '96!
Zupelz - Create and solve jigsaw puzzles
with your own images.The never actually made it out the door
but was mostly complete and my family had fun with it. This
might be resurrected for the phone.
And many others in a long list of experiments with uninspiring
names like "application14", some successful some not so much,
in games, graphics, and whatever else caught my eye that week.
e.g. Screensaver based on flocking behavior and a tool to make
your own mosiac from your personal photos.
