When I see the patterns a cuttlefish can create and the shapes a mimic octopus can achieve, it makes me want to teach these animals stupid tricks.
Can a mimic octopus raised in a lab imitate a human face? I believe they're endangered and a bit hard to find (haha) so I don't think we'll be seeing that anytime soon.
But why hasn't anyone tried to trick a cuttlefish or octopus of some kind into showing artificial-looking patterns? I'm sure there's limitations - no convincing right angles to be had perhaps. But I can't be the only person that's thinking like this.
