Giving myself a hand

So I took this photo a while ago, and it was okay. In fact I liked it a little better than okay. But I had this assignment in class, in which we created paper negatives. I can't tell you the process, because it is not my process to give away. Well, whose is it? My teachers.

When someone asked him, did you invent this process, and he nonchalantly said yes, it blew me away. Here I am sitting in a class with the man who invented his own process. Maybe I am a little naive and there are tons of people out there doing this, but still, that is pretty cool. And for the record, this process is pretty cool. Lets see you get this kind of effect with photoshop.

I think it looked even cooler when I printed it out. I did another one also, but don't have the file on me. Has anyone else out there come up with their own process?
