# Painting with Diophantine Equations

Solutions of the Diophantine equations x^{l} + y^{m} = z^{n} have been used for the generation of these pictures. The solutions in the x-y plane can be found as black dots in the pictures. Functions f_{i}(x,y) are assigned to each dot i and combined together. They are forming mountains, to which colorful contour lines have been assigned.
