ShaderGolf is a programming/drawing challenge where there is a canvas scanned top to bottom, uses 16 colors, there are 2 variables called c (color) and t (time), and there is a program called 'shader' that executes when each pixel is scanned, and the program is just literally a single expression. the t variables increments after each pixel is scanned.c is 0 per pixel by default. Here are some example patterns:
Line: 15 - !(t % 257) * 15
Colored stars: 15 - !(t % 46) * (15 - t % 16)
Colored circles: t * (t >> 7) >> 3
