    This is a personal thing!!! Twister2d is one of my favorite old school effects, it's also one of the first things i tried to golf to fit into a dweet (and I failed miserably :-)) I have retried tried (and failed) a couple of times, but this is the first time i actually managed to get the damn thing to fit without compression. I had to scarifice colors to maintin an interesting animation. Perhaps I'll get it next time :-) #twister #twister2d
