Had to share this - incredibly intricate crop circle.

Is there symbolism behind the cube within a sphere? And the texture of the cube is interesting.

Perhaps the sphere represents Earth, Sun, Moon, and/or Man.

"Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six." -Revelation 13:18

The cube in the subject crop formation would have a 3D volume of 216, or 6x6x6.

Earth’s precession cycle is 6x6x6! years,(!=factorial) or 25,920 years.
25290, 216 and 666 all have a digital root of 9.
The earth is tilted 23.4 degrees. 234 plus 432 (234 backwards) = 666.
The complimentary angle of 23.4 degrees is 66.6 degrees.
The moon's diameter in miles is 10x6x6x6.
Degrees latitude between the North Pole and the Tropic of Cancer is 66.6. (same relationship between the South Pole and Tropic of Capricorn)
Degrees latitude between the Arctic Circles and the equator is 66.6.
Earth's orbital velocity is 66,666 miles per hour.
Gravity = 6.666 X 10^-11 M^3 /(KGxSEC^2)
The sum of row and column totals on of the Magic Square of the Sun is 666.
