Circus clowns rejoice! The age of peddling a unicycle while juggling oranges and tying balloon animals just got a little easier thanks to
Bruce MacLennan Trevor Blackwell. MacLennanBlackwell designed an electric unicycle that uses gyroscope technologies to control pitch and yaw so you don't fall on your red, honking nose. The gyroscope ensures that the unicycle is upright; forward and backward leaning controls the acceleration speed. These are not available for for sale yet, but you can build your own with $1472 worth of parts.
BONUS: Isn't that a totally excellent mock turtleneck? [Thanks, Rose!]
