Cheap 1$ light tent / light box

Here's a super cheap light box from DoItYouself.com - "Ever wanted to do product shots but don't have the bucks to spend on a proper light tent? Why not build one yourself. This lightbox will cost you less than 1 $ as it only uses 5 sheets of paper. After 15 minutes of folding and cutting you are set!" [via] - Link.

This is quite possibly the coolest thing I've read in months: in order to combat light pollution, city officials in Reykjavik, Iceland, "will turn off street lights on Thursday evening and people are also being encouraged to sit in their houses in the dark." The clincher: "While the lights are out, an astronomer will describe the night sky over national radio."
