The clothing market is a strange nut to crack. Some companies garner a reputation for quality immediately, and others take years to reach that same point if they ever do. None of these companies have ever made a t-shirt with internet connectivity, as far as I am aware.
Someone had to do it. This is "tshirtOS", and it's exactly what the name suggests. It's a t-shirt running an operating system, and it's even 100% cotton! The t-shirt is a prototype at present, and may never become a reality. It's the sort of weird futuristic thing that leaves you completely stumped. Would you want one?
Their concept suggests that the shirt could come with an LCD display (no word on the subpixel layout), a microphone, and a camera. To the joy of photographers everywhere, it could come with Instagram support too, so you could potentially share your finest images on one t-shirt. It really is an odd design.
Cleverly the video never mentions the cost of the prototype, but we'll guess it wasn't low. Something about working a screen, microphone and camera into a t-shirt doesn't seem cheap.
Hippies in the '60s tie-dyed their t-shirts. With something like this, all you need is a high-enough resolution snapshot of tie-dye. It all depends on how great demand for the shirt is. Their site, tshirtos.com, does redirect to Facebook, so it could be an elaborate hoax. Even if it is, they have to be given credit for a very creative online joke.
