These are some programs and games I have written. All include source code and are licensed under GPL version 2 and/or version 3:
FreeSeat . a ticket booking and sale management application. Written for PHP and MySQL.
Pageturner . A program to automatically turn pages of sheet music while you play, or otherwise trigger pre-programmed events in reaction to sound. Written for Linux (PortAudio and FFTW), might compile elsewhere. Demo video
A Pushover Remake . A little 3D remake of the old "Push-Over" Amiga game. Written for Linux (SDL and OpenGL), might compile elsewhere. Demo video
A Breakout Remake . A little 3D remake of the classic "Breakout" game. Written for Linux (SDL and OpenGL), might compile elsewhere. Demo video
A Stunt Car Racer (sort of) Remake . this started like a remake of the excellent Amiga "Stunt Car Racer" game but has since evolved into something else. Written for Linux (SDL and OpenGL), might compile elsewhere. Graphic level editor included. video 1, video 2
picFX . A mathematically-oriented picture manipulation Amiga program (it might difficult to find a machine that still runs this in 2021!) Written for the Amiga m68k (AmigaE and MUI).
