The TrueDepth camera on the iPhone X is capable of capturing 50 facial muscle movements and mirroring them on one of
several cute characters, from an alien and unicorn to a panda and (yes) poo.
With its blinking blue ball of a hero and morbidly
cute style, it earned
several sequels, gathered a cult following, scored its main
characters spots in Nintendo's Kirby franchise and, most recently, showed up on the Wii's Virtual Console.
