I visited Tokyo / Japan after two years living in Madagascar (talk about culture shock) and was so amazed at how orderly a crowd that could have otherwise been chaotic moved throughout these cramped spaces.

Regardless, I would love to see what some of these "nudge" gestures look like in the U.S. How can we better design not just spaces but how humans interact with them?
