This is a great reminder that these projects are pretty accessible these days. The hardware is reasonably priced, and the code can either be written (or scavenged) pretty easily.

I don't say that to take away from the hard work and exceptional execution of this project, but rather as a reminder that we should all get off our butts more often and make something. In the end this is stuff that almost anyone with enough motivation can tackle (though perhaps not with the same panache).
