2010: Odyssey Two Easter Egg - Using the Zero Gravity Toilet

In the movie 2010: A Space Odyssey, the movie crew and director created an homage to the first movie. In 2001, there is a great moment on-screen as a character reads the instructions for a zero gravity toilet. It's an amusing scene.

Every time you see something written on the wall in 2010 that looks technical, it's actually the same instructions for using a zero gravity toilet. If you watcht the movie, you will see them everywhere.
