Big Stable KFm3 Delta. This is a delta wing that is nice to fly :-) I find it very relaxing because it is not hard to control.
Bitcoin Pong. An echo service for Bitcoin (Deprecated, with current fees it's not easy to do this.)

FreeDFD Two friends and I built this when we were still learning how to program. It's still in use today! See the demo. More than 450k downloads!
Damas99 Checkers program. I spent most of 1999 playing with this :-) I lost the sources. This review says: "The author calls his program 'very strong' and that is somewhat understated. While it isn't world class, it certainly plays very well indeed." It works with Wine.
emqbit-bench Compare the speed of floating point operations with different setups (Kernels, compilers, etc).
Touchscreen filters I finished the work that Andy Green started. I'm proud of the Group filter.
Minimalist library for a simple genetic algorithm. Used for this project.
ncurses chess clock :-)
