Model of an ambiguous solid.
Look at it from one direction it appears to be a cube, and from the opposite it appears to be a cylinder. Hold it up to a mirror and you see both at the same time.
The 4x model is a group of four of the shapes merged together to produce the illusion of either 4 connected cubes or four overlapping cylinders.
The models ending in correct have been reworked to use a more mathematically correct construction method. They will have a 30 degree up from horizontal viewing angle.
