Talented Ben Caulkins is a fan of LEGOs and Master Chief. So what is a fan with too much time to do? You make a full size wearable LEGO Master Chief helmet of course. According to Caulkins, it’s made “completely out of Lego except for the visor, which is a modified motorcycle helmet visor.”

Built like a brick (no pun intended), it is padded and extremely comfortable… but it’s also very hot. To see more of Caulkins’ Master Cheif LEGO helmet, check out his flickR here.
