A CNC machine, a thin sheet of what looks like birch ply and "100 or so rivets later" Andrew Thomson had the geodesic pendant lamp you see above. Thomson's an avowed Bucky Fuller fan; when last we looked in on him, he was turning old Coroplast electioneering signs into a geodesic precursor for the lamp you see above.
Thomson, by the way, is one of my favorite types of ID'ers: the unsung workaday guys who aren't looking to be the toast of Milan but are instead steadily developing their books and their skills in local applications. On his blog, Alabama-based Thomson documents projects he and his buddy Jared* have pulled, like turning wood from a local barn into a bed that looks better'n what you'd find in West Elm, and producing tables, benches and counters for local restaurants.
Best of all, he takes copious before and after pictures and isn't shy about documenting both the screw-ups ("The whole thing... got stuck in the planer a few times") and the glue-ups. And something about seeing shop photos where you can see the guy's hands working the router makes it all seem so do-able. See for yourself here.
*Jared, you need to nag Andrew to get your last name up on that site!
