During PÖFF - Black Nights Film Festival - in Tallinn, the film venues are adorned with kinetic sculptures by Kaarel Kurismaa. The sculptures of drums, bells or radios randomly make some strange sounds. I enjoy how these sculptures come as a surprise, whether you discover them by their look or their sound. The Solaris shopping mall has plenty of them, which is great, as the mall was originally planned as a cultural center.
