While you might see a CRT by the side of the street and think noting of it, Ryan Mason has come up with a novel use for five of them in a row called the Cathode MK1.
This set uses the Unity game engine along with an Arduino board to spread games across five tube TVs arranged side-by-side.
In order to keep project costs down, Mason’s gaming rig is restricted to displaying a game signal on one TV at a time. This makes gameplay even more interesting, especially considering that the way that each TV handles a loss of signal contributing to the experience.
Several games are available for this unique system, including Long Pong AKA Pooooong, where a ball bounces from screen to screen as shown in the clip below.
