Yes to Scratch and animations. The Pi stuff takes too long for a club that lasts half an hour, though the older ones enjoyed it.
Mine have also enjoyed taking apart the stack of dead laptops that we seem to have accumulated - it's much easier to let them go for scrap after that! They are UKS2 though. The younger ones mainly like to explore the programs they have used in class or in earlier years. Lots of 2simple drawings and similar. They also like Duck builder and other strategic games.
