Thurston, now at the University of California, Davis, found a particularly striking eversion in which the sphere's initially unwrinkled surface develops a symmetric set of bulges along its equator.
Moreover, topologists have already proved that every eversion must pass through a distorted shape in which at least four sections of the surface meet at one point.
Kusner discovered a surface that resembles the halfway point in the original Morin sphere eversion, when the inside and outside are equally exposed.
Deciding whether a sphere eversion based on this principle would work, however, required additional research.
When Kusner conceived of his sphere eversion, there was no graphics software for modeling the type of energy-driven transformations that he had in mind.
We did not know ahead of time that the Evolver would be successful in producing a sphere eversion," Sullivan says.
Sullivan and his coworkers visualized the eversion in a variety of ways, cutting away parts of the surface or making the sphere transparent to reveal its inner contortions.
Morin's polyhedral model of a sphere eversion makes it easier to keep track of where all the pieces of a surface are going during a transformation.
