I'm attempting to build something alone the lines of the attached photo I found on etsy. I'd like to able to input some arbitrary function that will determine the depth of each individual piece of the plane based on its x and y coordinates, that way I can embed a more complex pattern on top of that random static of the example. My initial thoughts are having a wave-like bulge in the center just to add some more visual interest to it all, but I'd like to be able to input any function so I can play around with what looks best.
