You may recall (although I won’t fault you if you don’t) engineer James Bruton previously building an omnidirectional motorbike on two balls. But do you know what’s better than two balls? “Three balls?” Agreed, but James decided to go the less is more route anyways and made an omnidirectional motorball that balances on a single ball. To each their own. Now make one that balances on no balls at all and we’ve finally got hover technology.
