Gyration has an interesting wireless keyboard and mouse combo. While the keyboard is your basic wireless fare, the mouse is a bit different. You can use the mouse on the desk like normal, but you can also use it up to 30 feet from the PC without needing a hard surface. The mouse can even be used in the air and still function normally. The 2.4GHz RF receiver provides a 30 foot range and the batteries for the mouse are rechargeable. The keyboard and mouse will function with Windows 98 SE, ME, 2000 and XP as well as Mac OS 8.0 and higher.
