The digiParrot: more annoying than the real thing

No, you're not looking at the guts of Duracell's robo-origami answer to the Energizer Bunny. It's the digiParrot — a prototype toy (we presume) that apes a whistled tune in those peculiarly annoying sounds only a child could withstand. Set two of these birds up side-by-side, whistle a bit of Crazy Frog, and you'll get an infinite loop that only a length of rope and unstable chair can resolve.
