This Wii-Mote hack is made from an actual controller for Nintendo's Wii Console. It's made with 3 types of %100 hemp string. Apparently this wouldn't really hold up to rigorous play. Still, it's sort of a stoner gamer nerd's fantasy. Even if it's only a show piece.
This is an original hand made creation from Dhreck.com. You can read more about the creation and see more images here.
The blog also tells you how you can go about making your own hemp enhanced Wii-Mote. The device won't hold up to real world experience very long though. Especially if you really get into some Wii Sports and start sweating into the hemp fibers. Gross.
