TIC-80
A made-up games console with 240×136 pixels and 16 colours that has become the demoscene's favourite sandbox for tiny intros and live coding.
Created by Vadim Grigoruk, better known as Nesbox, and released as open source in 2017. TIC-80 is a so-called fantasy console: a machine that never existed in hardware but has fixed, deliberately stingy limits on resolution, palette, sound and code size. Programs are mostly written in Lua, with editors for code, sprites, maps and music built in.
Those limits made it a natural platform for sizecoding, and several parties run dedicated TIC-80 competitions for intros from 256 bytes upwards. It is also the engine of Byte Jams, where coders write effects live to music – the same idea as Bonzomatic, only with pixels instead of shaders.
