   What do you mean by "coupled together"? You mean each one's frequency
directly

   affects the next one's frequency, and the next one, and looped back
to the first?

   That makes my head hurt. %^P It's kind of like time travel, where
everything 

   affects everything else...  Still, I like the idea. (even if it does
cause migraines...)

  That makes sense, since miniscule changes are "propagated & amplified"
around the

  feedback loop... this thing has got to be TOTALLY unstable! How cool!

  Yeah, i'd say so... sounds totally unpredictable. Guess it's time to
try and build

  something like this... wonder if you could use 555 multivibrators
instead of 

  the regular "transistor" multi's..?

  Let's get those ideas flowing!
