#6 A ‘learning moment’ for me Thanks for embedding the video.
#7/8 Thanks.
#12 Ultrasonic soundbeams from above… Hmmm
#15 Interesting… the Tinyurl worked btw
#16 You again? i guess i use a tinyurl next time. I agree with ‘The rice video is cool, the original story is not’

This is done in elementary electronics:

1 O’scope with x and y inputs.
2 signal generators one x and one y.

Spirograph fun; it is just that simple.

Add another source connected to the z input for extra effects (Z is brightness).

watching the rice vid a few times now has me wondering if the same energy patterns would emerge if you used a different medium than
rice.

for instance, if you use sand instead of rice would you just get a finer detailed pattern at the same frequencies, or something entirely different, visually.

now, if you do get a notably different pattern
(mearly because different mediums should
impart some of their own energy signature
into the waveform (or corrupt it)

-and there is a relevant correlation between these energy/resonant patterns and the crop circles.

would their be something about the energy signature of rape seed (which is the plant a large majority of the circles are drawn in)
that needs to be factored into decoding the circles.. (the real ones, not the hoaxes)

..i wish the sound on this PC was working…

anyway, just a thought.
