This is pretty old news for some of you and even I heard of it about a month and a half ago when it was posted on Engadget. This is a one-of-a-kind custom made t-shirt that has lights to notify you of new emails. The concept is cool but redundant at the same time. I even like the design of the tee. Anyway check out the video to see it in action.
