Hack: Optical Mouse in a Classic Mac Mouse

A friend of mine sent me this cute little hack: how to build a modern optical mouse into a classic ADB mouse's housing. Simply solder the button to the left button of a new mouse, route out the old mouse's shell to accomodate the electronics of the new mouse, and solder on a USB cable to the new mouse's board. I like the fact that they found a USB cable in the same beige color as the original mouse.

So bust out your soldering iron and get to work! Bonus points if you integrate a touch sensitive scroll "wheel" under the large button.
