Useless Machine was on The Colbert Report!
After letting Colbert try the machine, Mark explains that it's only function is to turn itself off. The audience laughs and Colbert says "I'll tell you what it does Mark...it breaks my heart."
I guess I should mention that the machine will be featured in the next MAKE magazine and that was why Mark brought it on the show!
My mind is officially blown.
Mark had sent me a heads-up letting me know about this, but I didn't receive it until after watching the show. I'm a regular viewer of the CR so for me this was especially sweet. Thanks Mark!
