We spent the whole of one Christmas fiddling around with ideas and then he went away and ripped a cheap cam apart to see what could be done. He documented it on his site - http://www.hoagieshouse.com/IR/ The Chicony Twinklecams are almost exactly the same inside as the cam featured in his strip down. Basically, it is a simple matter of opening the cam, removing the little red filter and replacing it with the developed, but unexposed negative - usually found at the start of a series of negatives. On my Twinklecams, I used a couple of bits and, if you cut them approximately the right size, you should be able to get away without making any little rigs or using glue to hold them in place. The cams themselves will see in IR once converted, but you ideally need a light source if you intend to play outside at night. Inside, with the lights on, you will see interesting things as shown on Geoffs site, but, if you have IR lights then you can mess around outside in the dark. A normal torch, with a full bottle of coke held in front of it makes a very cheap (but awkward) test light.
