These feel quite good even on my old 2G iPhone! Lots of tweaking to get them to feel right… There’s an iPad port too… But who knows how smooth will they run on it? I love how you are forced to release stuff you can’t possibly test on the final hardware. Feels so wrong!
I have been using Anemona on my iMac for quite a while. It’s one of the very best screensavers i ever have. Do you know how to tell if a design is good? Ask a kid what he thinks. By the way, my kid loves Anemona.
