a SCIENTIFIC explanation for crop circles, ice circles, etc..

Gotta agree with Astranax -- there's nothing scientific about the explanation. It's a "personal opinion."

In order to have a scientific explanation, you have to actually measure (and observe) what you're talking about and have studied documented cases. You would need to present evidence that the shrimp are in the material and what the density of shrimp needs to be to cause certain patterns. You need to show why the other explanations of this phenomena are wrong and yours is right (showing crop and ice circles that are Lissajous patterns.)

Given that the Earth and Moon and Sun obey the laws of physics and that they have known cycles, you have to explain why the snow crop circles have only appeared in the past 10 years or so and are never noted or documented earlier. Or worldwide.

Then you have to explain why the people at www.circlemakers.org... are lying about making these formations and show how the complex ones are derived from Lissajous patterns (and what frequencies and how strong.)

THEN you would have a scientific explanation for it.
