Big Bang! THIS MIGHT BE INTERESTING TO A COUPLE OF PEOPLE?
I didn't think to screencap any of the background's progress as it was pretty quick and easy (ALTHOUGH PAINFUL ON MY FINGERS.) I only started to get worried (and screencappy) when I had to leave my laptop hibernating to go to sleep and it was quite grindy when I got back to it in the morning. Going L-R, cap 1 is when I went to bed, cap 2 is when things were running very slowly, cap 3 is when OpenCanvas stopped letting me edit anything (oh that was a fun five minutes), cap 4 is the finished product!
