This sculpture, called "Boy's Day Out" is made of driftwood pieces by Heather Jansch, a British artist. Check out her website. I think the way they are displayed adds so much to their beauty too.
How cool is this sculpture by Yvonne Fehling and Jennie Peiz? I found this on line while searching for something for a student. Don't you wonder how they organized it, how they moved it to a gallery, and what their studio looks like?
My 3-Dimensional Art Class will be doing tape sculptures next. Here's a site with some great examples and directions on how to do it.
