The Turquoise Band

The machine room of a university on a winter evening, seen through a tall glass wall from a dim corridor, inside under white fluorescent light a double cabinet one and a half metres high with cream-white doors with fine ventilation slots and small locks, across its top a turquoise band above a dark grey band, both plain and unmarked, at its upper right a narrow panel with a key switch and small glowing lamps, a hand turning the key, two terminals on a table glowing soft green with blurred lines, grey tape reels stacked on a trolley, warm corridor lamps mirrored in the glass.
