Cunning design is a wonderful thing, and this triangular bundle of smarts is almost meta! Rocketfish's Sound Prism is exactly what it says it is, a three-sided speaker bar with a twist (metaphorically speaking.) Inventors, CRE8 Design studio, cooked up the clever idea of using the empty space created by a folded Apple Smart Cover. This fella neatly slips into the cubby-hole of the folded case, and attaches itself magnetically. It's Bluetooth, so can pair up with any compatible device, but won't look quite so snug as when used as nature -- or rather its creators -- intended. How much for a slice of the Pythagorean action? That'll be 80 rectangular dollars, sir.
