Turning a webcam into a see-through infrared cam

IR photos
A few photos taken with the modded IR cam. The photos are blurry and the quality is low
(thats a trademark of Logitech quickcam)
Night vision ! I shot a beam of infrared from the TV remote onto my hands and shot
this pic in perfect darkness!
See through capability! On the left is a shot from a newspaper. I completely
striked out a heading text with a permanent marker. As you can see, it is impossible to read. And on
the right is a closeup shot of the same text. But the IR cam saw through the Ink and the text can
be clearly read, "The Peace Maker" !

My eyes, taken in a dark room
I increased the 'gamma' option in the QuickCam program settings. The image in the left is
my hand in darkness. The right image is when I rubbed my fingers together, that made my palm warm.
Notice that the fingers appear brighter and clearer in the right image
A closeup shot of a label on my CPU, in the dark. The word "Coloreal" can be clearly read
This is a TV remote, with a button pressed. When the button is pressed, an ifrared beam is shot out.
The IR cam clearly detects and shows the infrared rays
A plug in the darkness. In the right image, the same plug, but I pointed a TV remote at it
and shot out an ifrared beam
A burning candle. The usual tiny little yellow flame has been illuminated and the rays can be
seen at a wide radius
A hot ironbox. The edges can be seen illuminated
