ThinkGeeks existing collection of soft-circuit "instruments." You can choose from seven different drum kits, including the ubiquitous 808 and a palette of chip tune effects. The T-shirt's integrated recorder lets you build loops up to three minutes long and endlessly layer on the sounds. Just keep piling 'em on until your old-school hip hop homage has become an impenetrable wall of noise that washes over you as you walk down the street, proclaiming your geekdom in rhythm. And, of course, the included mini amp cranks all the way up to 11. Check out the videos after the break to see MC Lars and Dex Fontaine demo the capabilities of the personal percussion pullover.
