The galleries at the Character walk were a bit dissappointing, but we happened upon two unrelated installations that turned out (especially in comparison) to be quit interesting. The first was Nurse Clara, an installation piece involving a lot of backscratching. The second was a series of 3x5 photographs by Claudia Rannow, arranged so the viewer could change the order of the prints and thereby the story. An absorbing online version exists here.
