these are 'quicktime virtual reality' movies. you don't need quictime, flash and java are fine, however a high-speed connection is highly recommended. the images are interactive. click on a thumbnail or on the 'low' or 'high' links below each thumbnail, a new window will open and you can look up, down, and all around by clicking and dragging your mouse across the image. main page http://pdxvr.com/tours-project-66 individual vr's http://pdxvr.com/vr-66-248 http://pdxvr.com/vr-66-249 http://pdxvr.com/vr-66-250 next time i'll not let the girls run from the tripod and make them pose in the photos.
