Thanks Phil, I think you will like this version even more. It's a shape shifter.

That's nice too, but I think I prefer the first one - it had more reddish-hues than this one, and I think the reds make it "pop". I don't know how the colours are picked, but maybe your algorithm gives lower priority to red? Still, great work, and I love the way the shapes morph into each other.

bplus - That looks really good!
