Today I saw that both MAKE and Ohgizmo are talking about a lightning activated shutter release. An expensive but cool device if you want to trip your camera once a lightning bolt flashes in front of the camera. It works because most lightning strikes are more than one arc of energy. As the bolt strikes a few times in a tiny moment the sensor commands the camera to trip it’s shutter. Bingo, you have a photo. That’s cool and everything but I prefer to do things the old fashioned way. For most of my lightning photos I use a pinhole camera and just let it sit there for up to an hour. Do I get some good shots? I think so.

I’ve seen parallax barrier/lenticular kits that you can buy in computer stores in Thailand. It had some software (simple image manipulation, 3D title maker, and the lenticular program) along with a picture frame that had a screen of the ridged lenticular material. The whole thing looked very cool. I think it was being sold by a printer maker, but I can’t remember what one. I do a bit of stereo photography here and there and was quite intrigued with it, but sadly not enough to buy the kit. The free software in the DIY article should be fun to play with though. 
How cool, tiny name cards that feature your favorite
