Magnetic Movie (2007)
This enchanting little short was produced at the NASA Space Sciences Laboratory, at UC Berkeley in 2007, and has won a number of awards at film fests since. Snip:
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?.Magnetic Movie, A Semiconductor film by Ruth Jarman and Joe Gerhardt. (thanks, Marianne Shaneen!). Ed. Note: this video was previously blogged on Boing Boing Gadgets.

Fantastic!
I can highly recommend getting hold of Semiconductor's excellent Worlds in Flux DVD. In particular, their sound recordings/interpretations of epic solar activity are mind-boggling and soul-quivering.
Best seen on the big screen, in a darkened room (which is how I saw them), but here's a youtoob clip:

Also excellent are their discussions with scientists, in which the scientists answer an unheard question, which may or may not be "Can Science tell us everything?" Some great answers - really thought-provoking stuff, and an antidote to the allegation that Scientists are arrogant.
as Presteign's daughter, Olivia, saw the world in Bester's Tiger! Tiger!
I think my favorite part of this is the sound effects. They're oddly soothing.
What are we seeing? What causes this?
It's like a Björk video.
Semiconductor's stuff is beautifull
thanks for the reminder :)
It's kind of misleading, because that's not how it would actually look like. Magnetic fields aren't a bunch of lines any more than a contour map is how a hillside looks. The lines are just our way of graphing them.
would you see fuzzy glows?
SEDNABOO - it's art. It doesn't need to be accurate!
What I love about this work is how animalistic or botanic the waves become - twitching, growing, tensing and then leaping across the room. They're kind of friendly and threatening at the same time.
a great movie, but the ending was a bit anticlimactic. I kept on hoping that the magnetic threads would ensnare passers by, control them to do their bidding, and ultimately take over the world.
SednaBoo: But don't iron filings arrange themselves into lines when tapped on paper above a magnet? And can't you get the same lines in 3D if you do it in an oil suspension? What are those lines?
I genuinely don't know. Are the lines the filings arrange themselves into really "there" or not?

Senda, I thght u were gonna say fields weren't accurate b/c they have non-zero divergence. But insofar as virtual photons are 'real', yes, the lines are real.
So, I'm confused. Is this a CGI interpretation of what it would look like if we could see them?
The probing, non-closed field lines were disturbing to me, as a physicist. Otherwise, I quite like the feel of the animations - very reminiscent of tesla coil or jacob's ladder vibrating-but-fluid energy flow. Would it have been so hard to make at least superficially correct field lines?

SamSam@10: I think the iron filings are just lines because it's a slice. Same way if i took a slice of the earth you'd see lines where the core, mantle, crust, etc. But when you look at the earth it's not a bunch of lines.
Plus I think using relatively large iron filings 'pixelates' the picture. If you had real short and skinny ones I think it's look different.
This video makes my teeth hurt.
