The most famous "hidden" number in Disney and Pixar history is A113. This alphanumeric code is a tribute to classroom A113 at the California Institute of the Arts (CalArts), where many legendary animators—including John Lasseter, Brad Bird, and Tim Burton—studied character animation. The number appears as a "Easter egg" in virtually every Pixar film and many Disney productions: it’s the license plate on Andy’s mom’s car in Toy Story, the camera model in Finding Nemo, and even a code for a "1-1-3" emergency in Onward. Another significant number for the company is 1923, the year the Disney Brothers Cartoon Studio was founded, which is now the name of a signature restaurant on the Disney Wish cruise ship. However, A113 remains the definitive "secret handshake" of the animation industry, spotted by eagle-eyed fans in everything from the background of The Simpsons to the control panels of deep-space vessels in WALL-E.
