Colossal is a goldmine (ah, pun!) of wonders, and this artist / sculptor of goldfish is right up there at the top. Riusuke Fukahori paints onto a layer of resin, before pouring a layer on top and painting again, repeating this until a detailed 3D image is built up. I'm sure Fukahori isn't the first person to think of this - it's certainly a popular technique in photography right now - but I think it's very effective, and extremely well executed here. The depth and quality is amazing, and that embedded pourer in the first image adds such realism, he fooled me into thinking it was a photo at first!
