It's the main blower supplying the air mixed with the powder of hallucinogenic mushrooms in to main ventillation duct. I guess it was the only way to survive in company of males packed like pickles in the jar, without getting totally insane ?!
Hello most Dynamic One. This furiously fiery photo features the fine subdued details showing the blower control switch "on." But of course it begs the necessary question: "What exactly does the blower do? ... And why was it necessary? My guess, my hunch about this photo, is that this fiery furnace is something transposed from the deepest bowels of 1666, where the ghastly foundation for the World War I, World War II, the Holocaust and the Cold War were first envisioned. Blower Control... these nudnicks from 1666, whose evil has no end , just keep on turning up the heat. Oy. Michael.
