Taking the geeky fanboy t-shirt to a whole new level, ThinkGeek's just added this wonderful Spiderman tee to its collection that actually gives the wearer a Spidey-sense for when danger approaches from behind. But instead of a radioactive spider bite, a proximity sensor clipped to the back of the shirt provides the superpowers.

After all, no one in their right mind would ever turn down superpowers. But they always come with a catch: horrible mutations, deceased loved ones, tacky costumes. This is the best of both worlds, a stylish black tee and a side-effect free sensor that vibrates at varying speeds as someone gets closer than five feet behind you. It sadly won't be available until October, and will set you back $40, but that's a small price to pay for not having to face any personal demons. [ThinkGeek]
