"World's most amazing subwoofer has no woofer"
Building one of these sounds like a good arduino project. :-) Seems
like "all" you'd need to do is figure out a mapping between how far
you'd rotate the servo-controlled fan-blades in response to sound.
I also wonder if this technology can be used to make spatially dynamic
sounds that would be difficult to synthesize, much like a real leslie
rotating speaker sounds different than an emulated one.
