The OSMO Custom Social Network Wearable concept takes on the idea of wearing your social network. It's a flex-image fabric that could be customized to fit on any piece of clothing.
I've clearly been bitten by the e-shirt and electronic apparel bug, but this is awesome. The OSMO Custom Social Network Wearable would sync and communicate with your iPhone apps to detect buddies from geo-tagged social networks like Loopt. The OSMO Custom Social Network Wearable would also be able to display the images of others who are also wearing the flex-image fabric.
