This is going to be part of my Projects of the Month for May, coming out in 11 days. The idea was given to me by a teacher named Charlie Unkeless, who based his model and animation on the famous Necker Cube illusion.
Part of making this model work involves switching SketchUp from the default Perspective view to a Parallel Projection view.
If you want to see exactly how to create the model and animation, sign up for our Projects of the Month!
Anyone can design anything in 3D! http://www.3dvinci.net/
