This air vent is perched ominously over the entrance to my office at Logos Bible Software. Every day I pass beneath it at least couple dozen times. And every day, as I walk down the hallway, it seems to threaten me – as though it were about to suck me up into a vast warren of twisty tubes. That, or bowl me over with an angry blast of hot air.
So far, I have survived. But I leave you this photo as evidence, just in case.
