File:Doo-dah domain colouring.png

Sorry for the upload's slightly navel-gazing nature, I have looked at many spaceships in my program and this is my favourite one thus far (the weekender is grey because it's at a third of the full period, for each iteration's contribution to one channel's total value there is another offset by 7 of the same contribution to each of the others, so my flawed colour handling doesn't cause imperfections here) It currently isn't so good with edges that grow backwards beyond their initial boundaries from their canonical phases (it's hard to detect them when the frontend is moving forwards and every) but it seemed to work well enough here, I like it the most Also perhaps it could be used here for educational purposes, the dim cells of maximal-saturation purple behind the weekender show the doo-dah's use of its sparks
