+.SYNOPSIS
+    Draws a Triplexity
+.DESCRIPTION
+    Draws a Triplexity Fractal, using an L-System.
+
+    Each generation of the triplexity will create an equilateral triangle with a spoke and an incomplete total rotation.
+    
+    Multiple generations of this seem to alternate between even numbered triangle shapes and odd numbered "lines" of triangles.
+.EXAMPLE
