When creating videos, clipart images can be incorporated to help tell the story. In this video about Fleas, http://www.sciencefriday.com/program/archives/201102182, by Malcolm and Greg Sutton you can see the use of clipart. If you are interested in fleas here is a link to some fleas from FCIT: http://etc.usf.edu/clipart/mysearch.php?searchWords=flea&mySubmit=Search.
