TshirtOS is the world’s first programmable and machine washable T-shirt. Developed by CuteCircuit, it has a built-in LED display working as a platform for self-expression. It can display your Twitter messages, photos and videos as soon as it receives a command message from your Smartphone. And yet it is machine washable. A T-shirt like that won’t be cheap. Would you be interested in buying one if it is put into mass production?
