A German artist named Daniel Becker has created a beautiful series of images based on random phenomena inherent in math. One image, for example, visualizes the unpredictable distribution of prime numbers, while another creates a trippy fractal-looking thing from the meandering digits of pi (pictured). In one particularly fascinating image, Becker plots 30,000 results from pseudo-random number generators in three-dimensional space to show the hidden patterns that emerge.See them all at Random Walk.
