I went to an elephant show in Chaing Mai where trained elephants did all sorts of tricks. The most impressive trick was when they let two elephants create paintings. I gathered from what was being sold at the gift shop they could only do the exact same painting over and over. I’m also sure there was some sort of trick to it as a trainer was on the other side of the elephant that the audience couldn’t see, probably prompting the animal at the right times.
Nonetheless, it was pretty impressive.
