If you can find a more aptly-named item than the “Show Off T-Shirt” we’d love to see it. This tee actually has a graphic equalizer panel that is sensitive to sound, so that the red, yellow and green lights actually move to the beat of music playing nearby. Luckily, the shirt’s small, detachable battery pack has an on/off switch, in case you suddenly decide normalcy isn’t so bad after all. Requires 4 AAA batteries, which are not included. For better or worse, instant (if fleeting) fame can be costly, as the $92 USD price for this tee can attest to.
