Does what it says on the tin: Dumps a truckload of unicorn diarrhea on your world (or at least on the mini-map; in-game results vary). I'll be improving the concept soon, such as adding "themes" (autumnal, gloomy, etc.), per-tile color blacklists (configurable), more styles and shapes for colored areas, and anything else I can manage. Enjoy.
