RayKo Celebrates WorldWide Pinhole Photography Day - Sunday, April 27, 2008 (11am-5pm) | Bus Obscura Rides (12pm-3pm) | Meet the artists (3pm-5pm) Demos | Build your own pinhole kits | Two gallery shows. As a unique celebration of WorldWide Pinhole Photography Day, FREE bus rides on the oh-so-unique Bus Obscura will be available on a first come first serve basis only on Sunday, April 27, 12pm-3pm. The Bus Obscura is a passenger bus converted to a multiple aperture camera obscura using a rear projection technique that allows the individual images to flow into one another. As the bus moves down the street a 360 degree animated panorama is created inside.

Passengers sit in the seats as usual but instead of looking out on the real scene as it passes by, they see a real time projection of the same scene. The exterior view from the bus is projected onto the interior of the bus and the individual apertures create images that merge into each other and create a real time animated projection of the world outside. The bus becomes the camera and the projector and the audience sits inside.

Bus Obscura’s sound track reinforces the cinematic quality of the piece. Sound artists Colleen Burke and Walter Sipser have made soundtracks for each city the bus has visited. Because the bus is being realized in different cities and environments with different images, light, ambience and history, a new soundtrack is made for each venue.
