Added: Cardiff's Audio/Video walks

"A video walk is similar to an audio walk but functions quite differently because of the visuals. With a video walk the participants receive a small digital video camera with headphones. The tape that they watch has been previously recorded on the site with a professional camera and binaural microphones following the route, which has been prepared with actors and props. Then there is an extensive editing process using the acted scenes, sound effects, and video effects to create a continuous motion. The audience follows this prerecorded film on the camera. The architecture in the video stays the same as the physical world, but the people and their actions change, so there is a strange disjunction for the viewer about what is real."
