Kleinian Group Limit Set
00:00
51
Limit set for a Kleinian group. The corresponding tessellation is shown in low contrast. The limit set is just the parts of the tessellation where the tiles get very small. The limit set is black and […]

Parabolic Sunrise
00:00
96
Technically a kaleidoscope sequence using a non-euclidean symmetry. But to me it evokes an other-worldly sunrise. For more info, see http://brainjam.ca/tessellations.htm.

Kaleidoscope with Two Parabolic Generators
00:00
24
The underlying group has two parabolic generators, and the tessellation is equivalent to a checkboard that has been inverted in a circle centered at the origin. By animating the tiles, we get a (non-euclidean) […]

A Degenerating Group
00:00
23
Shows the tessellation for a group which is evolving towards being singly degenerate. Corresponds to Figure 10.9 in the book Indra's Pearls. The parameter is evolving from (t_a,t_b)=(1.97-0.866,1.97-0.866) […]

Quasifuchsian Zoom Out
00:00
24
A zoom out for the tessellation corresponding to the group defined in Grandma's Recipe in the book Indra's Pearls. (t_a,t_b)=(1.95+0.02i, 3). For more information see http://www.brainjam.ca/tessellations.htm.

Unwinding an Apollonian Gasket
00:00
24
A Grandma's Recipe group evolving from (t_a,t_b)=(2,2) to (t_a,t_b)=(2+1.2i,3). There is a freeze frame at about the 6sec mark where (t_a,t_b)=(2+0.1i,3). This corresponds to Figure 8.7 in the book Indra's […]

An Apollonian Gasket Unwinding
00:00
24
Grandma's recipe group evolving from (t_a,t_b)=(2,2) to (t_a,t_b)=(2,2+1.275i). The first frame is an Apollonian gasket, the final frame is a quasifuchsian group tessellation. For more information see […]

Quasifuchsian Zoom
00:00
24
A zoom into the tessellation corresponding to Figure 8.1 in Indra's Pearls. The group is defined according to "Grandma's Recipe" with parameters t_a = t_b = 1.87+0.1i, and has two generators. The tiles […]

Zoom into an Apollonian Packing
00:00
24
A zoom into the tessellation corresponding to a punctured torus group with Maskit parameter 2. This is an Apollonian packing, with tiles either filled in with text, or with a purple/magenta coloring. The […]

00:00
24
Tessellation for the continuously evolving punctured torus groups as the Maskit parameter μ goes from 2 to 2+2i. For more information see http://www.brainjam.ca/tessellations.htm.

Evolution Toward a Doubly Parabolic Group
00:00
24
This is an evolution toward the punctured torus group with Maskit parameter mu=1.64213876+0.76658841i, as described in Figures 9.3 and 9.4 of the book Indra's Pearls. The final configuration is a circle […]
