# Thermal Lens

> Hover any image to see it through a thermal camera. The lens renders a false-colour heat map (ironbow, rainbow or white-hot) with scanlines, a crosshair and a live temperature readout. The heat map is an SVG filter, so it works with images from any domain; the readout appears when the image host allows CORS.
