Andrew Salomone is kind of a genius. He's hacked a Brother KH930 knitting machine so it functions like a desktop printer. That means he can transform any design into a unique Christmas jumper.

And, he has.

London's KK Outlet is celebrating Salomone's invention in an exhibition entitled Oh Come All Ye Hackers, featuring a slew of revolting Christmas tops created with the hacked knitting mating.

On view through December 22, 2011.
