A113

A113 (pronounced A1-13) was the classroom number used by character animation students at the California Institute of the Arts. Many of its alumni (including Pixar staff) have used the number in their professional works. It appears in some way, shape, or form in every Pixar film. Although none have been found to date on Monsters Inc, on the documentory "Pixar: 25 Magic Moments" Pete Docter mentioned he belived that it was on one of the doors in a hallway inside Monsters, Inc..
