Ack! I knew I would forget to post a link to somebody who entered!
How could I forget the largest entry in the challenge, Bert (TheToadMen) and his 20x24 homemade pinhole image? Bert you can rest assured that I saw your image, I had about 20 browser tabs open trying to put that post together and I somehow missed adding you to the list. This one gets top marks for creative approaches to the challenge and I really enjoyed the image. I like your woodpile, it looks a heck of a lot more organized than mine does.
I'm very sorry, hopefully I didn't miss posting a link to anyone else. If I did please accept my apologies.
