The gag being a one-liner, I thought this video would be dumb from the description, but it's pretty funny. Carnegie Mellon grad Robb Godshaw is an artist-in-residence at Autodesk's Pier 9 workshop, a fabrication facility in San Francisco, and as such he's got access to some bad-ass machines like an industrial waterjet cutter. So what did he decide to do with it?
Create Alphaclamps, "an exploration of tools and their form. From the I-beam to the C-clamp, the latin letterforms seem to have a chicken-egg relationship with the letter-shaped tools that bear their name. Is the C the basis for design, or simply a descriptor of the form? Curious about how the other letters would work as tools, I set out to explore the mechanical utility of the forsaken letters of our alphabet."
Unbelievably, there are folks who did not realize this was a gag, judging by the comments on the Alphaclamp Instructable Godshaw posted. Oh, internet.
