Gonglue Jiang is a Harvard graduate who loves design. And technology. He, like most of us, probably ran out of USB port one day. So he built a prototype of USB plugin that never runs out; basically if you use one, you open one.
This clearly respond to a current issue we are facing as we are becoming more and more mobile (little hardware, little buses). But with solution like this one, no need to worry next time you buy a MacBook Air or a netbook or anything with as little as one or two USB ports. The Concept received the iF Concept Design Award for its ingenuity.
