    This video uses analogy similar to the previous video in this series, but now it looks at a 4-dimensional sphere, or S3 sphere. Also, the other 4-dimensional polyhedra that have already been analyzed are viewed using stereographic projections onto 3-space. The resulting images are quite spectacular.
