Meet the SPUD: a collapsible 24″ display that opens like an umbrella and weighs the same as a paperback book. It uses a HDMI cable or wireless adapter to connect to your smartphone, tablet, or laptop. The screen measures 21 inches wide, 11 inches high, and 14 inches deep when completely opened.
SPUD is washable and flexible. It is designed for dual-screen setups on the go. It consists of a projector and a projection screen and works with a variety of devices. More info is available here.
