I was inspired to start this thread because Urs (Handstand) Lesse started doing this with his own photographs. He took a high-quality picture and took a chunk out of it. Then he posted it here and asked us to figure out what the object was.
Great fun, but a lot of work for him, I thought, taking his pictures and doing this. But I finally realized I could do the same by finding very large photos in Google Images, then take a piece out using Powerpoint, (maybe there are other easy programs where others can do the same).
It would be great if people could post theirs and continue the game.
I'm reluctant to show you more of the dark portion, because I think it's going to get obvious fast then, but then I might be thinking that way because I know the picture already.
