I'm trying to create a video feed that will display a special effects rendition of a dance area on a nearby video board. Much like what many of you have probably seen in a children's museum. An example of what I'm trying to do can be seen here: http://exs.exploratorium.edu/exhibits/recollections/
I've been searching for hours, but as there isn't a specific search term I can think of, it's extremely frustrating. I would really appreciate it if someone can point me in the right direction or has another solution to how this can be done.
