Ever had the chance to play with a $40.000 thermal imaging camera? I was lucky to get my hands on one back in 1998 and here is what I filmed - my buddy's car. Enjoy!

Some details for you techies out there: The sensor of the camera was an array of 320 x 240 elements sensitive in the long-wave infrared range (i.e. heat). It was cooled by a Stirling engine to almost -200 °C (-328 °F) to minimize noise. The lenses were made of monocrystalline silicon, as glass is opaque for these wavelengths. Fortunately the sensor was fast enough to capture 50 images per second and the camera had a video output, so I connected it directly to my VCR and pointed it out of an open window to record this footage.
