Abstract shapes to simulate shadows of waves on the water's surface. Good for adding texture and depth to rivers, oceans, lakes, ponds, and more! Could also double as texture for the ground, or whatever your heart desires :)
Switching between black and white can give effect of both shadow and light on water's surface. Greater density can be used to show rougher seas, unless you want to show calm seas in which case use the texture sparingly; you can do this manually by controlling where you use brush, or set it to "Spraying Effect" and changing both particle size and density in the settings.
