Off-topic, but from the article:

> Huang has a cool thermal imaging device for his phone that he used to make this photo of the Heirloom showing the heat distribution

I'd be really interested if this is an affordable solution. A FLIR camera would be nice to have, but they're really expensive. Does anyone know what model he's talking about?

EDIT: Thanks everyone, looks like they've come down in price significantly. Almost cheap enough to buy one just for kicks.
