Magnetic Movie from Semiconductor on Vimeo.

I’m not sure how this video was made, but it is really amazing to look at.

As rhetoric instructors spend more and more time teaching new media like video, I think this genre—the instructional video—will become an important skill for students in their own fields.

Here’s a description of the video:

The secret lives of invisible magnetic fields are revealed as chaotic ever-changing geometries. All action takes place around NASA's Space Sciences Laboratories, UC Berkeley, to recordings of space scientists describing their discoveries. Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent ‘whistlers' produced by fleeting electrons. Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?
