Ok I got really bored today (and we all know boredom is not a burden anyone should bare) so I decided to make my XB-Live Communicator a one ear attachment. This came in handy because I have a really mis-shaped head and the band that goes around the back of the head squeezes on me.
Anyways here is a couple pics, It's not really a mod as much as it is a 5-10 minute time killer, but I like the look it gives it none-the-less.

Crappy pic but it shows the basic design

Better Pic and close-up. The electrical tape is just there to hide the ugliness of the super glue attachment and the hot glue reinforcement.
It's not a great design and doesn't hold really well to the ear but it works and it kept me entertained for a bit and it looks kinda cool.
