Water in swimming pools changes its look more than in any other form its colour can be man-made and its dancing rhythms reflect not only the sky but, because of its transparency, the depth of the water as well. If the water surface is almost still and there is a strong sun, then dancing lines with the colours of the spectrum appear everywhere.
