The 'Show Off' t-shirt comprises a printed OLED, sound sensitive spectrum analyzer, a battery pack and a healthy dose of cool. It's designed to be worn in nightclubs where the display actually pulses in time to the music; each bar is sensitive to a different frequency.
It's not cheap at $92, but probably worth every penny. Just make sure you follow the washing instructions on the label. How long until we see animated ads on here?
