Use oldschool tools or retro hardware devices
Having one of those "where's my triangle?" days? Try changing the scene! Try the retro-scene: where people continue to make beautiful things on old, sometimes very old, computer hardware and game consoles and various random / weird devices.
We suggest you visit the Vintage Computer Festival to get your hands and play demos on real retro hardware. But if you don't have a 386 PC handy, you can start with retrocode on a modern computer using an emulator or compiler.

The demoscene thrives on productions for the Amiga, Atari, ZX Spectrum and many other makes of computers and game consoles. If there's an oldie-but-goldie platform you're interested in, just ask at the Graffathon for some tips and waypoints!
