One of the nice things about living in Arnhem is the Sonsbeek Park, a wonderful area of woods, meadows, and waterworks adjacent to the city center. My apartment is located a few steps away from the park, which fills with people, fountains, concerts, and exhibitions each summer.
The park is sponsoring a sculpture show with works by about 30 artists scattered throughout the park. There's a guidebook and a long trail that leads around the whole exhibition, and I took some time exploring it last week. Some bits are pretty mundane: disks on the ground, masks, paper statues. But a number are really clever and intriguing: here is a small gallery. The show continues through the month and is free.
