One of the things I regret about Prague is my own stupidity: I forgot to charge my camera! So it died, and I have no photos of my own to share of the lovely openwork iron sculptures by Čestmír Suška, a Prague-based artist, that I saw on the roof of DOX Center for Contemporary Art. The show brings together Suška’s Rusty Flowers series before the pieces return to their homes throughout the Czech Republic and the U.S. I loved the textured, rusty metal surfaces, but also the interior spaces of the sculptures, which gives a sense of playful lightness. The cut out surfaces interact with the light and their surroundings, allowing you to glimpse the hollow structure and its setting, and creating beautiful shadows.
