How many times have you heard the phrase “turn off your TV?” It is usually used as a call to action for couch potatoes who need to reform, but Bath-based designer Jack Archer took it as an inspiration to create this fantastic alphabet. It consists of 15 small televisions housed in a custom-built cabinet. Archer changes the letters by turning various TVs on or off.

The resulting typeface is oddly (and charmingly) low-tech-looking for having been constructed with machines. The time lapse video above shows the entire project from start to finish, including the set-up and tear-down of the TV cabinet. We would love to see a video of the setup spelling out scrolling messages one letter at a time.
