There are two mathematically relevant aspects about this design. 1-
Geometry: Dedicating my this year's work to triangles icosahedra are
a logical consequence that can't be left out! 2- Arithmetic: I
incorporated a number of primes into this piece. There are 19
icosahedra featuring 17 colors, together with black&white it's 19
colors. The appearence of each color on the icosa-balls amounts to 2
and 3 including 3 singles.
A ribbon of triangles forms an "endless" spiral. That's the basic
construction of this colorful bracelet. The gaps between the
spiral's loops are closed with additional pairs of triangles.
