This was my attempt at a radial tiling. I ended up with a curious ‘pulse’ or ‘shift’ in the pattern, causing a ripple effect, that can only repeat along one axis. This is yet be fully understood.
Below is another larger motif I made up. It can also be interspersed with modules.
A special thank you to Jaap Scherphuis for his invaluable input and to David Bailey for helping early on.
