Some guys calling themselves Team Hassenplug made a chess set out of Legos. This might not sound that impressive, but watch the video. Don't read ahead. Just watch the video.
Done? I KNOW, RIGHT? Holy fuck! It took four guys over a year and using $30,000 and more than 100,000 Legos to create that 12.5'-by-12.5 monster (no pun). I don't know that I've ever featured an Impressive Act of Nerdery as impressive as this. Hell, I don't even want to play with it, I just want to watch it being played. It's gorgeous. Please, visit Team Hassenplug's site for more specs and details; and infinite thanks to Joseph P. for the tip.
