Bathroom Collaboration

From Steve Jobs by Walter Isaacson:

"So he had the Pixar building designed to promote encounters and unplanned collaboration.  "If a building doesn't  encourage that, you'll lose a lot of innovation and the magic that's sparked by serendipity," he said.  "So we designed the building to make people get out of their offices and mingle in the central atrium with people they might not otherwise see."  The front doors and main stairs and corridors all led to the atrium, the cafe and the mailboxes were there, the conference rooms had windows that looked out onto it, and the six-hundred theater and the two smaller screening rooms all spilled into it.  "Steve's theory worked from day one," Lasseter recalled.  "I kept running into people I hadn't seen for months.  I've never seen a building that promoted collaboration and creativity as well as this one."

Jobs even went so far as to decree that there be only two huge bathrooms in the building, one for each gender, connected to the atrium.
