The money. It's all about the money. Just kidding. I love to see others use the stuff I've made, but I often make things I know no one will use, but I still love it. Usually because it's different or it's stretched my abilities. I'll make something just like something that someone else has done before, just to see if I can do it. Then I just put it some place and never use it again, since I have the original done by someone else.
