Bit-Tech has posted a Giganta Optical and Giganta Optical Smoke review
Why should optical mice require a special mat?...
The way optical mice work is well documented but just in case you are not aware, put simply, optical mice work by shining a light, (LED), on to the work surface and "reading" back the reflection with a camera. The mouse takes a continuous series of " snapshots" and since the reflected "picture" will be different as the mouse is moved, movement can be calculated by the mouse's built-in processor. Thus it follows that the work surface must have a degree of reflectivity and some sort of irregular pattern for the camera to work with. Surfaces with zero detail and mirrors make very poor mousing surfaces.
