Recompute.
Some bloke has created a cardboard computer case for the Greener Gadgets Design Competition. A little bit bulky but i kind of like it. And apparently the Core2Duo innards won’t set it ablaze, if you were about to point out the seemingly obvious.
Other entries to the competition include a concrete external hard drive and a printer that uses tea and coffee dregs as ink (although these two seem to be more about “statement” than any sort of usefulness).
