If you can't get 'em to produce infinite clean energy in your perpetual motion machine, why not repurpose those magnets into a keyboard? That's what Embotec's done with their appropriately named Magnetic Levitation Keyboard. The design apparently aligns the magnets in opposition which forces the keys apart before succumbing to the pressure of your digits and German supermodels. Now please, by all means, do not use it near the magnetic desk. Else you might find yourself levitating over the Grand Canyon wearing a smarmy ascot and feathered hair.
