From the You've-Gotta-Be-Kidding-Me department: Kouichi Okamoto built this entire chair out of aluminum wire and...nothing else. The whole thing is made from aluminum wire with no fasteners at all, it holds itself together like a chain-link fence. Even more impressive, this is the sum total of tools he used to build it:
Pair o' pliers and a jig. Crikey.
Called the Composition Chair, it took six months to build.
Okamato, by the way, is a DJ and sound producer turned product designer. He's the principal of the Shizuoka-based Kyouei Design lighting and product firm, and you can see more of their wicked projects—some clearly revealing Okamoto's DJ background—here.
