The OGO on The Late Show with David Letterman

So we had an invitation to appear on The Late Show with David Letterman, and took the OGO along for Dave to try out - check it out: David Letterman in the OGO:

At the end of the show, David's guest Joseph Gordon-Levitt asked if he could try out the OGO too. So we took it out onto 53rd street and let him loose. Check it out: Joseph Gordon-Levitt in the OGO
