Dude, You really Need This! Seriously!

You like a Cosplay? Create your costumes and have a real fun with this? So you need this hoodie.

This Hoodie detects your movements and create the perfect lighting for your spell. Really awesome.

I only found this on ThinkGeek. If you find in another place with a good price, let the link on comments below

Makes me think on Avatar, The Last AirBender.
