Conformal projections to Euclidean space of Blaine Lawson's ruled minimal surfaces
in 3-dimensional spherical space realized with the real-time interactive CAVE
animator ``illiSnail'' created by Glenn Chappell, Chris Hartman and George Francis
of the NCSA 1994 illiView team.

Minimax triversion of the sphere, by George Francis, John Sullivan,
Chris Hartman, and Stuart Levy of the NCSA/UIUC,
Rob Kusner of UMass, Ken Brakke of Susquehanna University.
A sphere can be turned inside out without tearing if it is allowed
to pass through itself; the sphere eversion shown here was computed
automatically by starting with the halfway model (where the orange
and blue sheets pass through each other) and simplifying it
by numerically minimizing a surface bending energy.

Trajectories in the May-Leonard dynamical system, a highly simplified model
of populations of three competing species. It was generated by illiPhaser
[http://www.ncsa.uiuc.edu/VR/cavernus/PHASER/Phaser.html], developed by
Alex Bourd, George Francis, and Jonathan Manton of the illiView group at
the NCSA, University of Illinois.
