Every day, each online webcamera is capturing five time lapses. When one of the lapses is really cool, it is uploaded to YouTube for easy viewing by others. You can subscribe to this channel on YouTube and be alerted when new lapses are uploaded. The interface below shows the most recent 20 cool lapses.

If you are interested in downloading these, please see this directory of movies. If you use these lapses, please credit KCCI-TV and Iowa State University.
