calling all inventors... i need a gadget

I wish someone would invent a wireless mouse powered by a laser beam because I will get one! So I can lean back away from the computer table and be able to just point to whatever I choose to view... without the hassle of grabbing the mouse and placing it over a surface or using the keyboard to navigate. Just as remote controls were made for people who want to stay comfortable on their couches or beds and still be able to choose the right channel with the right volume for the perfect TV viewing. (In five words: ito ang hiling ng tinatamad)
