I have posted about various t-shirts that require batteries (here, here and here) and I have just come across a shop selling tees with a graphic equalizer like function. The designs on these tees react to the sounds around them making the wearer appear to be a total douche bag. They are a bit of fun though. Most of them are spoofs and/or probable copyright infringements but what do I know. Maybe they are legally licensed. Below is a selection from the store. They are all $45 and available from Jetsobox which appears to be based in Asia. you can also check out videos of the various tees reacting to the music.
So when you are going clubbing in one of these babies don’t forget your batteries. Your dignity on the other hand you will leave at home.
