Here at ThinkGeek we're constantly amazed at the never-ending evolution of new technology. Hey, it's our job. Take the lowly T-Shirt for example: In caveman times you had animal pelts... the Medieval era saw rise to the stylish burlap sack... next came lovely soft cotton and then synthetic polyester. Finally the modern space age delivers a fully functioning graphic equalizer in a handy t-shirt format. Party like it's 2999 with the glowing display on the T-Qualizer that dynamically changes with any ambient sound or music. This has to be the coolest wearable tech we've seen since the George Foreman backpack grill.
