Artist and designer Dan Rosenfeld felt Urban Putt, an indoor miniature golf/bar/restaurant in the Mission district of San Francisco, needed a little bit of magic inside its walls.
Thus Rosenfeld created “Sleepwalkers”, an installation that illuminates 3-inch tall figures that interact with its viewers.
As his site explains:
Participants are encouraged to put their golf ball into an entrance in the wall. After a few seconds of rattling, the ball becomes visible through an opening in the broken lathe, stuck inside the wall. The goal is to figure out how to get the ball out from behind the wall so it can be used to play the adjacent mini golf course.
They then “provide” the sleepwalkers with energy and a platform to jump off by putting their hand in the hole in the wall. The figures then run off to help eject the ball from the wall.
