xndraw

xndraw is a program to draw tileable shapes and wallpapers written by John O'Driscoll. It is written with free opensource tools, and is intended to be made freely available, and modifiable.

I wrote it to visualise tileable images, after seeing ceramics by Guy Crossley, as I couldn't see how to come up with new patterns without a drawing aid

Currently it's a fun toy. It could be a lot better at reproducability , have more patterns, robustness, the list goes on
