Los Angeles filmmaker Joe Penna, whose online persona is MysteryGuitarMan, spent 10 months making this stop-motion timelapse video to illustrate his wife Sarah Evershed’s pregnancy and the birth of their child Jonah Lane Penna (MysteryGuitarBaby). The video starts out with a car that has broken down, and the husband pumping air into the tires as his wife’s belly grows bigger and bigger. Then, violà, a baby!
