I've always wondered about the creative process on things like this. Does one go out thinking, "I'd like to paint a rock to look like a dog", then go and find a rock that looks like that? (How does one even develop an eye for something like that?! Never would've seen a dog in this rock if not for it being painted) Do they think, "I'd like to paint a rock! No idea what!" and find a random rock and paint the first thing that comes to mind? Or were they simply strolling and thought, "hey, that rock looks like a dog!" and went with it?

I'm not particularly artistic in this sense so the mindset of those that are is interesting to me.
