About the Design
Mathematically beautiful. This tangled textured design was created using a prime spiral: the prime spiral, also known as the Ulam spiral, is a pattern in which positive integers are arranged in a spiral, with the primes indicated somehow along the spiral (in this case points, which were used as a scratch point and graphic reference for the texture).
