Wow! Can’t believe I haven’t reported this one yet. Apparently the work you see below is in a way similar to Julian Beever’s artistic sidewalk drawings, only with one exception – it’s done with mosaic technique (when the artist creates an image out of many small different colored tiles). We had some optical illusion mosaics here on this site in the past, but these are absolute winners. The intention of these pools is artistic, and I believe that single drop of water won’t be used in them (although, it would be even better to use them for swimming as well). The most important is the 3D effect the author achieved. Which one do you like the best? Sharks are my favorite!
