Reduced complex fractions of the form z/w where coefficients of z and w are integers and the max(norm(z), norm(w)) is the denominator. Could also be described as coprimes (z,w) of the Gaussian Integers, Z[i] represented as fractions. The color here corresponds the size of the denominator.Via http://math.etutorworld.com/ #etutorworld
