This will be cool the first time you use it; after that, you won't be able to headbutt the keyboard fast enough to turn the damn thing off. Or at least that was my experience when I tested out the Mega Man Effect, a Windows/OS X accessory that plays the Mega Man fanfare and shows a scrolling screen of stars every time you launch an app.
This isn't useable unless you're willing to sit through a thirty second shrill, grating mp3 that will make you want to pluck the teeth out of your head with your thumbs every time you launch an app. But worth a one-off experiment and a grin? You betcha. Courtesy of Destructoid.
