Pinheads Unite

Today, April 25, is Worldwide Pinhole Photography Day. I'm sure you can feel the excitement in the air. Here's how it works:

1. Build a pinhole camera
2. Take pinhole photographs today
3. Submit them to the WPPD site

This is the fourth year the event has been held, and you can see previous years' pictures from all over the world at the WPPD picture gallery.

Today's contest is only a few hours old, but they already have pictures up from New Zealand, the Netherlands, and the United States.
