This is awesome, but the unicycle bit is actually just icing on the cake. It's those nifty, nifty wheels that interest me, with their complete freedom of movement along any vector. A two, three, or four-wheeled version would be just about as useful, though not as spooky.

The wheels were rather impressive. I can't wait until they or something similar become the norm in personal mobility. Going to have the sweetest little scooter for going to the shops with when I'm much older.
