My Tug-in-a-Jug at http://www.mocpages.com/moc.php/403116 illustrates another (serendipitous) method similar to making a layer of loose 1x1 round plates: Use blue 3L friction pins or 2L axle pins instead. Shaking the layer horizontally causes the pins to settle into a semi-ordered 3D texture evoking the surface of the ocean in various sea states. Permalink

Using medium azure plates with clear 1x1s on top looks really pwitty.
Yep! That's my favorite technique. And by changing the color of the plates/bricks underneath, you can give the water a sense of depth. Also, a lighter shade of blue under clear plates can give a nice frozen look. Permalink
