Problem:

First off, I'm not looking for online lectures.

I am trying to find creative commons licensed videos of live cells moving around without annotation or anything extra. I would prefer a few minutes of video of tumorous somatic cultures of eukaryotes in vitro and at a few different magnifications but it doesn't really matter. I don't have a microscope or I'd just get some pond water and look at multicellular organisms. The license must be creative commons or public domain, the author must be citable, and the subject organism should be known.

Any ideas where to find such video?

Does anyone know how to go about this search to explain it.
