wolkd can display mathematical functions, frame-by-frame animations (and even animated GIFs!) on RGB LED strips, and can be controlled via a [web interface](#user-interface) — with your laptop, smartphone or tablet. wolkd lets you write animations in terms of either a pixel's LED strip index or x and y coordinates using a [mapping file](#mappings). And wolkd has a 256 color ANSI terminal debug mode!
