If you want cool.....
If you want cool movies of the Solar Photosphere, go to the website of the Solar and Heliospheric Observatory (SOHO) satellite.

Check out the "Best of SOHO" page. They have MPEGs that will knock your socks off. I had no appreciation of the extreme violence that is part of the Sun's everyday existance until I saw those MPEGs.
