"Grimace shows you what emotions look like. Pick from joy, surprise, fear, sadness, disgust and anger and set the intensity for one emotion or a combination of your choosing.

They are understood worldwide and hardwired into our brains from birth. For artists, Grimace can serve as reference library for facial expressions. "
