Cool, it's like computer aided routing/correcting and I remember seeing this a while back when the guy first came up with the idea. Nice to know that it's progressed to being sold to the public now. There is also this one which is closer to a traditional CNC router.

That's just a sampling of videos that are on Youtube about this machine, there are many more. Usual disclaimer: Don't work for them, don't make any money promoting this machine, just think it's a clever idea and want Santa to bring me one.
