It's still at 100% most of the time, a few small gaps of less CPU usage (seen in CPUInfo Docky). But I don't get the slowdowns as earlier, so it's apparently not stuck in a tight loop or anything, just doing its thing with whatever CPU it can get unobtrusively, it seems.
I was thinking, BTW, if you (or any users) are missing the coloured light bulbs, then an alternative could be to just put them up there as a static image, that would look almost as festive together with the falling snow.
Best regards,
