Uni christmas tree ornaments

I went to Bluewater (quite a large out of town shopping centre or mall) on
thursday. One of the shops had a loo roll holder with a little santa (2") atop a
uni suspended above it. when you pull out the loo roll it makes the wheel and
his legs move in a riding fashion.

Could make those visits a little more interesting. The only trick I could get
him to do was idling but with some surgery I think 1 or even no leg riding would
be more than possible. <g>
