Ring (do/undo/redo) is a dynamic light installation created specifically for its site at the Lichtfest Leipzig 21 by Ben Busche of Brut Deluxe and Miguel de Guzmán. The Lichtfest Leipzig commemorates the demonstrations of October 9, 1989, in the East German city of Leipzig, which served as a decisive catalyst for the start of the Peaceful Revolution that ultimately led to the fall of the Berlin Wall.
