I remember once reading about a Device that essentially turns fan blades or was it more like a solenoid pushing the air up and down, anyway the end result was turning essentially the room or even house into one giant 'boom box' forgive the cheesy 80's term.

Anyway that was what about 5 years ago i've not seen or heard anything since, I'm starting to wonder if it was a practical joke... ?

Bertus

 

Or perhaps a rotary woofer:

That's the thing.... no idea, but those 2 are also interesting ideas too.
