Thank you for using its name. I first saw it on TV showing someone hand painting a design on a car (probably a Rolls Royce on Top Gear) and thought it was brilliant in its simplicity, but didnt know its name.

I just made one with a dowel and a big superball, but I've seen one that they put a skateboard wheel (with bearings) on the end so it rolls.
