Has anyone used the free 3D animation program, Blender? Or have your students used it? It looks like a great tool for those interested in delving into 3D animation (especially since it's free!), but the learning curve appears pretty steep. Drop us a comment in the box below and let us know your experiences. I'm thinking of adding some of the tutorials for Blender to my 7th/8th grade technology class for the new semester.
