The SMS Guerrilla Projector is a one-off device made by Troika Art and Design in London. Operating under the bat-signal principle, the projector shoots a text message onto whatever surface you point it at, letting you paste your own personal messages on road signs, movie screens Ã¢â‚¬â€ even some innocent schlub’s backside. Keep it clean, kids. The mischievous device also has a cell phone built into the handle, enabling you to dial in your clever slogans from afar.
