Your eyes don't deceive you. That is a shirt that takes you out of imaginary air guitar or "slappin' da baaass" land and into a comfortable t-shirt with a functioning guitar built into it. It includes a mini amp with tone knob that clips to your belt. It doesn't play pre-canned music mind you. For better or worse, the sounds emitted during your jam sessions will be yours. This is accomplished with a magnetic pick and your fingers. All major chords can be played.
A little further investigation at ThinkGeek.com reveals a video with some nerdy rock guys using it on YouTube. Enjoy.
