Jordan Mechner, creator of the original Prince of Persia, has been posting his original development diary entries to his official blog to coincide with the exact date they were written 23 years ago. Each post is a treasure for fans of the games, but the October 20th entry is particularly special: it contains the animation reference video for the Prince Mechner shot in the Reader's Digest parking lot in 1985, using his kid brother as a model. Anyone who has ever played this game will know every once of David's motions by heart. Amazing.
