@thurloat It's like the crazy "camouflage" on WWI battleships, that was supposed to make it hard to figure out which direction the boat was actually moving (thus making it harder to take up a proper firing position and/or aim accurately). Everyone will start wearing crazy masks in public and only take them off at home or in trusted company.
@ink_slinger Apparently haircuts that obscure face and even just some eye makeup is enough to fool most non-depth sensing algorithms.
So long as you modify or obscure 2+ of the key feature points (eyes, brows, nose, mouth, chin). I guess changing it frequently would still be an issue with that approach.
