For my sketch, I had water be the “wet” thing and a cliff be the “sharp” thing. To do this, I used the bezierVertex() for the water, then put it in a for loop so it would repeat across the screen. I also had to tweak numbers quite a bit to find the style that I wanted. It really helped to visualize where the control anchors were. For the cliff, I just used beginShape() and endShape(CLOSE) and put a few vertices in. I kept the cliff concept clean cut to emphasize its sharpness. I wanted the water to be a bit more dynamic, so I made a for loop inside a for loop to go across and down. The roundness of the top of the waves and motion captured in it reminds me of water rushing over into a waterfall – something that is very wet.
