About this 3D model

A sphericon is a combination of two cones one of them being rotated along the z-axis. It is most well known for the way it rolls or rotates. When you rotate a cone, it spins around in a circle. When you rotate a sphere it just roles, changing displacement. When you roll a sphericon it rocks back and forth like a cone but is also moving forward. It is analogous to the impossible cube because at first glance it is confusing.
