Jobs had become fascinated by the idea of serendipitous interactions. How to make sure that everyone mingled together? He hit upon a plan: Pixar’s headquarters should have just a single pair of large restrooms off the main lobby. People would make new connections or revive old ones, because everybody would have to head to the lobby, brought together by a shared human need to urinate.6
This is fascinating because he had the example of Bell Labs where they accomplished the same serendipity by long wide corridors and round tables in the cafeteria.
Also, Bell Labs put together very diverse teams and often more than one so they would compete with each other.
