Thought some of you might be interested in this story I saw on Yahoo!

That's pretty cool. Many years ago when I worked at the Pittsburgh Playhouse, I walked into the dark theatre one day and stumbled around on my way to the light switches. In the dark I noticed there was a little hole in the wall and light was coming in from outside. On the backdrop I saw a huge upside down image of the scene outside, just like the pinhole camera described in that article! Unfortunately, I didn't have a 30'x60' piece of film handy to earn my place in the record book though ;-)

But if you look carefully you can see lots of examples of this in everyday life. Just a couple days ago I noticed something related in my bathroom, which has a small window. On the wall next to the window I noticed a very diffused image which was blue at the bottom, transitioning to green in the middle and then to red at the top. I thought that was interesting, but it suddenly dawned on me that it was a very out-of-focus upside-down image of the scene outside: the blue was the sky, the green was the trees and the red was the stones in my driveway!

link doesnt work for me but is this the obscura camera in the hanger?
