Just yesterday SorbanGeeks reported that a Drumming Santa powered by USB is available in Japan. I just found this very seasonal USB Gadget available at the IwantOneOfThose Gadget store. They ship international.
The Drumming Santa interprets with blue light effects the following christmas carols Jingle Bells, Joy to the world, The First Noel, Silent Night and one more IWOOT says "so terrible we were unable to identify it". That said, this is the most kitsch powered by USB you can get for 20 bucks.
IWantOneOfThose sells the Drumming USB Santa for about $21.43 (£12.99).
