Truchet Tiling in Houdini
I saw a bunch of really cool examples of Truchet tiling recently and thought I'd try to implement it in Houdini. To create Truchet tiles, you start with a couple of shapes and randomly copy them to a grid. When arranged this way, they produce connected lines and unusual patterns, and you can make a bunch of variations with different "random seed" values. This may be fun to package into an asset one day - check out the .hip file here.
