Thermal projection mapping allows you to see how hot something is before you pick it up. The technique is a combination of FLIR One and projection mapping. It can be used to paint surfaces with the amount of heat they give off, as measured by a thermal camera.

The result is way cooler than the explanation, but it’s not always easy to do.”]
