I apologize. I did not mean to post the actual videos. They are available at the Cornell University Plant Pathology Lab youtube site.
I also found an interesting paper and video about the use of a doll made up of different plastics to monitor changes and deterioration in different environments. Unfortunately most of the images of the doll were before and after, but it they might be helpful.
