I wouldn't call this art, but it seems this pig "Pigcasso" enjoys painting canvases, and people are paying money for what the pig is painting. So......if a pig can do this for fun, then we can too. It's an amusing story and the pig is mimicking his owner. It takes intelligence to design something original that is art and I guess this pig is smart enough to learn by watching his owner, and he's probably playing. I've read about elephants learning and memorizing how to paint a picture of a tree, but I don't know if they make the cerebral connection of recognition that humans do when they see an image that represents something that has meaning. I wonder if this pig has other pig friends he paints with... and does he hog all the art supplies? I wonder who signs his work.
