A ball may include a spherical shell, and apertures defined in the spherical shell. The apertures may be formed in the spherical shell based at least in part on a N-frequency tessellation of the spherical shell. A method of forming a ball may include molding a first hemisphere, molding a second hemisphere, and coupling the first hemisphere to the second hemisphere to form a spherical shell. The spherical shell may include apertures defined in the spherical shell based at least in part on a N-frequency tessellation of the spherical shell.

7 . A ball comprising:
a hollow sphere; and
apertures formed in the hollow sphere based at least in part on a N-frequency tessellation of the hollow sphere, the apertures being disposed at an intersection of line segments that form the N-frequency tessellation, the line segments including at least:
a first line segment having a first length, and
a second line segment having a second length different than the first length.
8 . The ball of claim 7 , wherein the apertures include:
first apertures having a first size; and
second apertures having a second size different than the first size.
9 . The ball of claim 8 , wherein:
the first apertures are disposed at an intersection of at least three first line segments; and

14 . The ball of claim 7 , wherein the apertures have an equal spacing between edges of adjacent apertures.
15 . A ball comprising:
a spherical shell; and
apertures defined in the spherical shell, the apertures being disposed at an intersection of line segments of a geodesic polyhedron, the apertures including at least:
first apertures with a first diameter, and
second apertures with a second diameter different than the first diameter,
