This Christmas get t-shirts for all your geeky friends. No I don't mean that you need to hit Fifth Avenue or offend them by giving them a makeover but something that is more up their alley. Check out the uber geeky and dare I say cool Electronic Music Synthesizer Shirt. This one is not your ordinary shirt since it comes equipped with a playable music synthesizer that includes eight-voice polyphony, high-quality sampled sounds and even a stylist retro amp box. This fully-playable, t-shirt-based music synthesizer shirt requires 4 AAA batteries, has an adjustable tone knob and features removable electronic parts for easy washing. So buy these in bulk to jam with your friends, even if the Fashion Police will unleash its wrath on you. They are available on Think Geek.
