Rotation Bug is, in part, an exercise in artistic humility and accepting that an error in layer rotation produces a piece that is often more interesting and aesthetically pleasing than our original intention.
Bugged is now default for 75% of outputs.
2% have an artist signature in the background pattern.
You can fix/unfix the bug by clicking 'b' on the keyboard.
'd' and 'l' will switch between dark and light backgrounds.
'r' will randomise the tilings.
'b', 'd' and 'l' will reset to original tilings but 'r' will cycle through the same patterns after reset.
