[math-fun] Dragon and Twindragon animations

I created some dragon animations that might be of interest. The first is a twindragon animation that sweeps through the self-mapping angles, pausing briefly at points of interest (twindragon, tame twindragon, rectangle, reverse tame twindragon, reverse twindragon): https://www.karzes.com/anim_twindragon.gif The second is a Heighway dragon animation that also sweeps through the self-mapping angles (while retaining their difference), pausing briefly at points of interest (Heighway dragon, triangle, reverse Heighway dragon): https://www.karzes.com/anim_dragon.gif Tom
