Two wheel balancing act

Here's a DIY Segway.. Remember the much hyped and overly expensive two wheel urban miracle? This guy even made a one wheel version and all the guidelines to make it yourself...now that's sharing an idea! They all look nerdy though, take ages to get to the office, but if ya wanna be cool? Go build one! Look Dad what i made you for Christmas, ...no no no, the other button ...ouch.
