Undergrad Dan Yuan's image here was first runner-up in MIT's annual Weird Fields contest where students generate psychedelic visualizations of vector fields. (Last year's winner here.) The patterns in Yuan's visualization remind me of the background of a Tim Biskup painting.
UPDATE: As the MIT press release and BB reader Tom Zeller point out, the Weird Fields visualizations bear a striking resemblance to sections of Gustav Klimt paintings. Link
LinkTo help students understand electromagnetic force fields, Professor of Physics John Belcher and colleagues at the MIT Center for Educational Computer Initiatives developed a computer applet into which students put the mathematical expressions that describe a given field. "It then pops out a visual representation of what the field looks like," he said.
