English: This is a plot/heightmap of a function of two variables that I have discovered. It shows the region from [-4,-4] to [4,4] with grayscale values adjusted so that white/black matches the maximum/minimum value in the plotted region. The function formula is following: logistic_curve(angle_rad(sin(x^2),sin(y^2),triangle_wave(y),triangle_wave(x))).
