I'm using a magnetic resonance imaging (MRI) machine to fMRI trial subjects while they experience club-like conditions. This means I need loud, high-fidelity speakers, flashing multicolored lights from multiple directions, etc. Big speakers usually means big magnets, obviously a problem in an MRI machine. Any ideas?
One for the historians amongst us.
One of the companies I worked for (many years ago) was founded by a brilliant engineer by the name of (Sir) Charles Parsons. He invented many things but perhaps one of the strangest was the Auxetophone (originally patented by Short) - a compressed air gramaphone sold in the U.S. as the Victor Auxetophone. (see http://en.wikipedia.org/wiki/Compressed_air_gramophone)
There's even a Youtube video for your entertainment.
