But at a recent conference the Japanese inventor of Pac-Man unveiled the original drafts of how the iconic video game would look.
Toru Iwatani was due to speak at the Festival of Games conference in Holland when he casually displayed a simple scrap book filled with his original sketches for the game.
Drawn on simple graph paper they give a compelling insight into what was to become a pop culture icon.
And they also show that the game’s unique look did not differ much from its original concept through to finished game.
Each one is marked with a stamp that means ‘Top Secret’ in Japanese, giving a sense of how truly revolutionary his design was in the late 1970s.
