Note from Liz: Exercises from Sara Froehlich's Photoshop Elements classes at Eclectic Academy gave me the ideas for the spheres and photo cubes.  We're using a somewhat different approach for each, but they are both adaptations of Sara's basic ideas.  The symmetric designs are from a set of directions I worked up after much on-line discussion  with Jane and JoAnn on the PSE Student Group.  The copper metal styles that several of the examples use are ones I developed in Sherry London's Photoshop class at Ed2Go.  The students in the College Grove class have experimented with their own ideas and taken the examples well beyond what I originally gave them.  They are a very talented group!
