Yeah I saw this a while ago on YouTube, it really is truly amazing, especially how the elephant will repeat strokes over the same line to make it darker. My only concern, is the treatment of the animals. Are these elephants being abused in the process of being trained? It's one thing to exploit their 'hidden talents' to make a buck out of wide-eyed tourists, but another to be cruel and mistreat them. I wonder if there is any way we can check if this is or is not the case?
