The famous #Wang-tiles playground, originally built with the now-defunct Stagecast, has gone offline, probably forever. For now it’s still working on the Internet Archive, with a selection of 2-edge, 3-edge, 2-corner, and 3-corner tiles, plus unrestricted (1-color) tiles, with all kinds of crazy op art.

"MicroUI" is a 1.1kloc #IMGUI library in C by rxi, with no dynamic allocation. This version is hacked to run on SDL. It maintains a queue of up to 4096 drawing commands from the library to the app of four types, MU_COMMAND_{TEXT,RECT,ICON,CLIP}, or sometimes maybe JUMP? #small-is-beautiful #noalloc
