There is a version of maths wall art that treats mathematics as decoration - colourful fractals, equations written in chalk fonts, posters that say things like "mathematics: the language of the universe." These are fine, but they are about the idea of mathematics rather than any specific piece of it.
The Axisophy Signature series does something different. Each print begins with a specific mathematical object - a prime number distribution, a fractal construction, a number-theoretic spiral - and renders it at high resolution. The result is a piece of wall art that contains actual mathematics, not just the aesthetic of it.
