Cool.  Some of these are quite mesmerising to watch...

The "How to draw mushrooms on an oscilloscope" video is quite instructive 
too,

Here's a cool device that creates fascinating patterns on an oscilloscope:

I buit one some time ago and it's fascinating to play with. It would be an 
interesting gadget to have at a synth meet or a gig without requiring the 
use of any of your modules. I recreated the original magazine article and 
saved it as a pdf so all the info is there, including the PCB layout (single 
sided).

It's a fairly simple circuit and would be inexpensive to build if you can 
make your own PCB. The only parts you may have finding are the 4136 and the 
FETs.


BTW, I'm still not exactly how the phase shift works on OSC C. If anyone can 
explain it to me I'll update the blog post and the pdf.
