Anything that allows it to move easily and smoothly and reflects the laser (a clear, or very light colored desktop will not reflect properly and so the mouse may not respond accurately.) I've used things like large note pads (turned upside down so that the tan, or brown rear cover is what the mouse slides on) with success, but don't use something with lots of light colors as they absorb the laser and don't give good reflections.
