Overview
Demofruit is a love letter to the C64/Amiga/DOS graphics and music demoscene of the 1980s and 90s, built to run on the Fruit Jam. Six classic demoscene effects have been ported using Claude Opus 4.8 to run in Arduino on the RP2350-based Fruit Jam
- Starfield forward-warping star field with bouncing text
- Plasma palette cycled summed sine waves
- Chrome Sphere a dual-core raytraced renderer
- Valley Run wireframe terrain flyover is a nod to the vector-landscape demos
- Rotozoom - tiling bitmap texture tranforms with rotation and scaling and lens effect
- The Juggler - port of Eric Graham's 1987 Amiga Juggler raytracer — an animated character juggling three mirrored balls over a checkered floor
All of the demos (and the launcher screen) are accompanied by tracker MOD songs created by kqvc that playback using the PocketMod MOD player.
