Boy's surface is described here as a 'half-way model' for the eversion of a 3-sphere. If I follow a distributed set of points on a sphere up to this point, do they fall on one single surface, or is it actually to two of them? For example, the North and South poles in Jean Pierre Petit's "Le Topologicon" described here
I'm watching this, this and more so this and this video and I'm trying to recreate this visualization for myself. The image in my profile shows a surface drawn from a parameterization of Boy's surface from R. Bryant, but is this actually only a hemisphere?
