NEW YORK (AP) — Tired of the selfie? Get ready for the “thermie,” or as I like to call it, the “hottie.” That’s when you take a picture of the heat emanating from your body, using an infrared camera that attaches to the back of your iPhone. It sounds unlikely, but it’s coming.

Apple stores started selling the $349 FLIR One this week. It puts thermal imaging within reach of people who probably have never considered it before, and it opens up a whole new way of looking at the world. Warm things show up bright on the iPhone screen, while cold things are dark. It’s like everything glows with its own light.
