the internet museum of flexi, cardboard and oddity records
A great record - excuse the pun - of some weird and wonderful ways in which records have been pressed on cardboard, metal, stamps, and so on: The Internet Museum of Flexi, Cardboard and Oddity Records
extremely rare records
If you ever find yourself with huge amounts of cash going spare, the eBay seller Extremely Rare Records could be just what you need. As they say: "Our goal is to offer all the best records, most of which are hard to find, in one spot."
They're either a gigantic scam, or very skilled at tracking down all kinds of musical releases and memorabilia that were thought to be gone forever. Or it's a long-term fanboy who's finally decided to sell all of their things.
Got £12,000? Pick up a handwritten, signed Elliott Smith set list. Only three grand available? How about a set of very early K Records cassettes? Truly, it's an indie rock record collector's dream.
subliminal acoustic manipulation of nervous systems
US patent for a device to affect human behaviour using sound. From its abstract:
"The method and apparatus can be used by the general public as an aid to relaxation, sleep, or sexual arousal, and clinically for the control and perhaps treatment of insomnia, tremors, epileptic seizures, and anxiety disorders. There is further application as a nonlethal weapon that can be used in law enforcement standoff situations, for causing drowsiness and disorientation in targeted subjects."
