Falaco Solitons

Notice the contrast "dimple" above the third black spot. Once you find the surface defect project downwards at an angle of about 30 degrees and to the right (the solar angle at 4 pm) to the black spot on the far right hand side of the picture. Once you have found one correlation you can find all of the other dimples that project into the other black spots. The fact that the oblique projection yields a circle (and therefor is conformal) is a clue that the surface dimple is related to a minimal surface. The actual surface dimple depression is about 2 mm (but is highly contrast distorted in the photo). The black spots on the bottom of the pool are about 10 cm in diameter. The pool depth is about 30 cm.
