Amazing Embrace
Remember when PDA stood for something other than personal digital assistant? It can again with the Hug Shirt, a high-tech garment that simulates the experience of being embraced by a loved one. When a friend sends you a virtual hug, your cell phone notifies the shirt wirelessly, via Bluetooth. The shirt then re-creates that person's distinctive cuddle, replicating his or her warmth, pressure, duration and even heartbeat. And, yes, the Hug Shirt is fully washable.
