Spidron

A standard spidron consists of two alternating, adjoining sequences of equilateral and isosceles triangles.

[1] A spidron is a plane figure consisting of an alternating sequence of equilateral and isosceles (30°, 30°, 120°) triangles.

The spidrons can appear in a very large number of versions, and the different formations make possible the development of a great variety of plane, spatial and mobile applications.

These developments are suitable to perform aesthetic and practical functions that are defined in advance by the consciously selected arrangements of all the possible characteristics of symmetry.

The surface could be used to create an adjustable acoustic wall or a system of solar cells that follow the sun in a simple manner.

Various folding buildings and static structures could also be developed on the basis of my geometric investigation which may have utility in space travel.
