Maybe you didn't find those layered fish paintings as impressive as I did but, after you watch this video showing how Riusuke Fukahori makes them, I think you will change your opinion. This guy is a perfect human 3D printer. Impressive skills.

From the video description:

Japanese artist Riusuke Fukahori paints three-dimensional goldfish using a complex process of poured resin. The fish are painted meticulously, layer by layer, the sandwiched slices revealing slightly more about each creature, similar to the function of a 3D printer. I really enjoy the rich depth of the pieces and the optical illusion aspect, it's such an odd process that results in something that's both a painting and sculptural. Wonderful.

Thanks to Sploid reader I-C-winner for the tip.
