Thermochromic Slow Resolution Display

A slow resolution display made out of standard lightbulbs and thermochromic paint.

This display lives at the intersection of digital control and analog output. A matrix of lightbulbs painted with thermochromic paint allows for an image to appear and dissipate analogously to the temperature of each bulb.

The overall effect defies our ordinary understanding of materials and time within technological systems.
In this case, lightbulbs are used for heat and not light. And the refresh rate of an image is constrained to the time it takes for the material of the screen to change temperature.

More on thermochromism here.

Here, we’re using 40 watt bulbs. They take a few seconds to warm up and turn white and a couple minutes to cool down and fade back to black.

Built by Alex Abreu, Taylor Levy, and Che-Wei Wang

Thanks to the dozens and dozens of you who helped make this project possible!
