Smooth hard lines

[tin-soldier]

Is there a method anyone's found to remove/smooth the hard lines which form in the ripples? In other words just have the blurry mesh gradient moving around?

I also wanted to make this change, in Gradient.js, replacing noise *= 1.0 - pow(abs(uvNorm.y), 2.0); with noise = smoothstep(0.0, 1.0, noise); seems to do the trick
