Swinging is already a pretty great way to spend some time, but swinging inside a mirror-lined room turns the humble pastime into something awesome. This room is an installation entitled The Phoenix is closer than it appears. It was created by artist Thilo Frank at the Museum of Modern Art in Aalborg, Denmark. The room measures 4 x 4 x 8 meters and has no windows, but the mirrors make it appear to stretch infinitely in all directions along with infinite reflections of yourself happily swinging away. Fun, freaky or a bit of both? You’ll have to travel to Denmark and give it a try.
