I found this over at Xbox360Fanboy.com, Zoozen has created a Xbox 360 case mod known as the OVO 360.

Whether or not you like the look of it, one commenter on YouTube likened it to a Apple Mouse, you have to admire the quality of the job.

It will be interesting to see if it is offered  as a purchasable mod down the track, but I couldn't see it being cheap.
