There are IFS-like fractals that can be generated using small iterative functions. Here are examples in JavaScript that can be remixed (and they are very short, only 140 characters or less). E.g.: https://www.dwitter.net/h/fractal and https://www.dwitter.net/h/fern

Dwitter is a cool social network where JavaScript programmers can share demos, fractals, art algorithms and interactive code viewed on <canvas>.
