Sensurround

If you went to see Earthquake at a cinema in the 70s, chances are that it was in "Sensurround". All this really meant was that the seats vibrated due to an emission of low-frequency sound - and lots of women left the cinema with flushed faces at the end.

Doctor's claimed this new effect damaged your eardrums, but it sure was fun. You can re-create this effect at home by sitting on the washing machine while watching the TV.

The full list of movies featuring a Sensurround soundtrack is Battlestar Galactica, Earthquake, Midway, Rollercoaster, and Zoot Suit. (Is it just me that's thick or is "one of these things not like the others". I can understand why you would want bowel-rumbling effects with the first four - even the titles sound a bit sensurround-ish - but why the hell would you need Zoot Suit in tackle-wobbling sub-Woofer vibration?).

Just thought I'd ask . . .
