In one of my classes (not a photography class, actually), we were asked to do photograms. There's absolutely no skill involved at all. You just put the paper down, pile objects on the paper, and expose it. Then develop it.
I did about 20, and picked the 10 best for my class tomorrow (these are 8x10). These are a few of my favorites. The quality is bad because I just stood over them and took the picture with my digital camera. I'll post better ones once I get them scanned.
