[sdiy] Tape Head Derived Thereminish Thing

[John L Marshall]

Years ago there was an experimental arts magazine (I can't remember the 
name. I must be getting old.) that included a magnetic patch on one page of 
one issue. If I remember correctly the patch was about three inches square. 
A tape head could be swiped (Doesn't it annoy you that some credit card 
scanners ask you to swipe the credit card.) across the patch in any 
direction and sound could be heard. Pretty cool! Hmmm. Was the magazine 
called "The Source"?

Take care,
John
