Personal Soundtrack T-Shirt

For many of us, our iPods supply the soundtrack to our lives — but it's kinda hard to let everyone else hear it. An April Fool's joke turned real product, the Personal Soundtrack T-Shirt ($40; pre-order) overcomes this with a working speaker embedded into the front of the shirt that's attached to a pocketable remote which lets you select from more than 20 different musical themes and sound effects.
