Quipu

This is a workplace where a single circulation thread ties otherwise separate teams together in the only form that counts. The intent survives the construction, which is where most of it is usually lost.

Here, the route is deliberately indirect and passes every team once, so the walk to the kitchen is also the way you learn what everyone else is doing. The tolerance in that junction is tighter than the rest of the building, and it is the one place the extra work was worth it.
