Through at least the 1980&#x27;s, the Infinite Corridor at MIT [1] was one of the best interaction generators I&#x27;ve encountered. Every hour, half the student body would walk down the Infinite Corridor in one direction while the other half walked it in the other direction. It was a simply brilliant use of large scale architectural planning, as you encountered half your classmates multiple times a day. It&#x27;s still a powerful cultural factor but the campus building boom of the past couple decades has led to many students spending much more of their time sequestered in departmentally focused building clusters than was originally the case.<p>[1] <a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Infinite_Corridor" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Infinite_Corridor</a>
