ThinkGeek's got the perfect gift for that street performer in your life: an electronic drum machine T-shirt. The $29.99 shirt has nine different drum sets (everything from jazz to rock to chiptune) with seven pads each. To take advantage of all those sounds, you can loop up to three-minute-long tracks so you can lay down a beat and then increase the complexity of your tune. To top it all off, it comes with a hip-mountable amplifier that "goes to 11," you know, Spinal Tap-style — it's not the company's first instrumental shirt, believe it or not, but it might just be the coolest. The patent-pending (and machine-washable) shirt is for sale now at the source link, though it's currently backordered.
