What's astonishing is that this is not a photograph of goldfish in a tank. Japanese artist Riusuke Fukahori creates three dimensional images of goldfish by painting them, layer by layer, separated by very thin sheets of resin. You can look at them from any angle and they look just like fish. Watch a video at the link demonstrating how Fukahori does it.
