Some people have noted the unicycle-like Death Eater prop used by Harry and his friends in the Order of the Phoenix movie. I just saw that there’s a replica of it made by the Noble Collection, so if you’re into collecting unicycling knick-knacks this may be for you:
So that’s what it was… 
Scroled through the whole collection, and it’s prety pricy.
But there are people who will give money for something unique like that.
