Although all of these graphics are based on simple functions, it's possible to make stereographic projections that map out surfaces forming some very exotic manifolds. In the case of the tubes at the corner ends of the complex star below form a stereographic projection from all sides of the object under rotation. I put the PTSpace Movie on my Goggle plus page as my blog doesn't handle you tube movies very well. Access my Google Plus page with the flower icon at the bottom of my post archive list, right side of the page.
