We’ve heard a lot about how OLEDs are poised to change everything from televisions to smartphones. But a group of researchers at MIT Media Lab’s Fluid Interfaces Group are applying OLEDs too more mundane objects, too—like plain old rulers. And the results are surprisingly cool.

Glassified is a prototype by Anirudh Sharma, Lirong Liu and Pattie Maes, three MIT students who are part of the FIG group. Their device is simple, in theory: It’s a clear glass ruler, embedded with an OLED panel and a Wacom digitizer connected to a nearby computer. When you use it to draw a series of lines, the Wacom recognizes the pen strokes and performs an analysis on them, relaying that information back to you via its OLED screen. For example, it can tell you the angle of a triangle or length of a line, or the area of a polygon. But as Sharma and co demonstrate, it can also act like a game: Draw a couple of lines, and it’ll use them like a maze for a dynamic ball.
