"What the work of art looks like isn't too important. It has to look like something if it has physical form. No matter what form it may finally have it must begin with an idea." -- Sol LeWitt
I took a sculpture class this semester on a whim. I enjoy art, but I've never done much sculpture, and I haven't taken an art class in years--so why not?
The first project I did was an exploration of mass. I sculpted a head from clay (the professor modeled, because he couldn't get an actual model), made a plaster waste-mold from it, then did a plaster casting. Everyone else in the class did essentially the same thing--sure, there were variations in the way the heads were sculpted, but we all made heads.
The second project, however, was open-ended. We were given an introduction to a selection of sheet metals, wire, and tools; we were told to think about space rather than mass, and that we should include repetition and variation in the work. And that was it.
Do you want to know what I created? Take a look! I titled it "Selves." I think it turned out pretty darn cool. (But I wouldn't have created it if I thought otherwise.)
