Think Geek features a number of cool geek apparel and this is no exception. The latest t-shirt they’ve done is a proximity based light up heart shirt. What that means is you’ve got to buy two. One for you and one for your lover. While wearing the shirts, the closer in proximity the two shirts become the more hearts light up. In contrast, hearts will begin to dim the farther you are from each other. Less love. Check ‘em out at Think Geek. If you’ve got a girl that’ll share her love in this geekery than I say hold tight and never let go.

Boom!
