Some of my most unique ideas come from students. Here are two examples.

The Lion Cub bas relief was intended as a quick project for the after-school program that I teach. The student never finished it, but it gave me a great idea for a unique piece.

The pumpkin was another student project.  To finish by the end of class, she decided to leave the square shape and finish it "cubist style".  Another wonderful concept created by circumstance!
