Details

Paul Gailiunas [1] found a method that can produce spirals with three or more arms. This Demonstration shows 52 spirals made from intersecting -gons up to with all possible numbers of arms from 3 to 18. The basic polygonal tiles can be considered as bent wedges with three boundaries made of equal edges: a base of 1 segment, a convex side using segments and a concave side using segments. For fewer arms, several spirals with the same number of arms originating from different -gons are given.

These monohedral spiral tilings are nonperiodic, have rotational symmetry and tile the plane.

Controls

"arms, , ": select one of the 52 spirals with the given number of arms, made from a specific -gon, using segments at the convex side.

"levels": controls the length of the arms.

"edges": use this checkbox for enhancing the boundaries of the polygons.

"color count": set the number of cyclic colors selected from the color palette popup menu. Selecting "arms" provides different colors for each arm.
