Let me explain the concept of this T-Shirt: you wear one and give one to your partner. Then whenever you both are "in range", the pixilated hearts start glowing to full charge. This means your beloved is somewhere nearby and you can go over and give him/her a hug! When you are out of range the glowing hearts dip to two and a half. Essentially you either need to pick up two T-Shirts or one T-Shirt and a transmitter for the concept to work. Replicating the life power of your fav gaming hero, the hearts on the Tee indicate your life/love status: weird but cute, especially since Valentines is round the corner. The 8-Bit Dynamic Life features: - Glowing Animated T-Shirt Displays Your Remaining Life Energy - Buy as a Pair. When two shirts are within hugging distance all 6 hearts light up - Black 100% Cotton T-Shirt - Animated Decal is Removable (with hook and loop fasteners) for Easy Washing - Battery Pack is concealed in a Small Pocket Sewn Inside the Shirt - Runs for hours off three AAA Batteries (not included) - You need to buy at least two shirts or one shirt and a transmitter pack for the 8-Bit Dynamic Life Shirt to function correctly. It will cost you $11.99 for one and $24.99 for a pair. Via - Gizmodiva
