self-silencing cooling fan/speaker assemblies

The New York Times > Technology > Circuits > What's Next: To Quiet a Whirring Computer, Fight Noise With Noise

Dr. Sommerfeldt's system has four miniature speakers and four even tinier microphones set in a ring around the computer fan. The microphones and other sensors detect the noise of the fan blades and, with the help of digital signal processing and algorithms, radiate opposing tones from the speakers. The whole system can be tucked into the same space that a conventional computer cooling fan would occupy.

Wild prediction: Someone named in this story is getting a phone call from Steve Jobs tomorrow.
