One large black Japanese fan which has 360 degrees of articulation is timed to open fully over twelve hours and then to close for the next twelve.
A smaller but otherwise identical fan is centered on the first and describes its arcs in sixty second intervals.
If the fans begin their cycle as closed at twelve noon then the overall effect would be that of full dark at midnight and brightest at noon.
