Double Projection

Vertices of a rotating 16-cell, projected the 2-sphere by the Hopf map, then stereographically projected to the plane. Also, a still image with frames composited together.

Open and closed random walks with fixed edgelengths

by Jason Cantarella, Kyle Chapman, Philipp Reiter, and Clayton Shonkwiler

In this paper, we show that a random walk is (with overwhelming probability) surprisingly close to a closed loop with the same step sizes, and that closing up has very little impact on local features.

In particular, this suggests that local knots should occur at essentially the same rate in loops as in open chains.

Power Surge

More Mercator projections of level sets of sums of dot products, this time with the vertices of a regular tetrahedron.

Correlations

Mercator projection of the contour plot of the sum of the absolute values of the dot products of a point on the sphere with the vertices of a rotating octahedron.

In Balance

Mercator projection of concentric circles on a rotating sphere.

Map

Mercator projection of rotating great circles on the sphere. Inspired by what @roice3 is doing with TilingBot on Twitter.

Unfold

Linearly interpolating (in space, though not in time) between a double-covered octagon and a regular 16-gon

Follow Through

A morphing 11-pointed star.

Fall In

Stereographic projection of dots on the sphere.

Twist

Just some spinning line segments centered at points on the circle.

Loxo

Start with a bunch of points on loxodromes. Now rotate in space, then stereographically project to the plane. Finally, form the Voronoi cells of the resulting point set.

The aggressive video compression does this one no favors; see a better version along with source code at http://community.wolfram.com/groups/-/m/t/1291902 https://mathstodon.xyz/media/OsWh_UoCkHrl6fm7nkg

Oof. Another one destroyed by over-aggressive video compression. See the source code link for a better version: http://community.wolfram.com/groups/-/m/t/1286395

Caught

Voronoi diagram of stereographic projection of some spherical spirals.
