https://youtu.be/X3Q30UYgLfcI have been wondering about these ever since I heard that two old guys with boards created them.
The interesting thing is that they still appear despite one guy being too old now and the other one dead.
One interesting design is of representation of the Mandelbrot Fractal Equation.
and a sampling.

Those are nice fractal equations!!
Those aliens, such artistic tricksters!
Nice! It's too bad the aliens didn't stick around to explain their designs. Maybe farm fields are their Etch-A -Sketch.

Seems hard to believe that aliens traveled here from light years away just to show off their artistic skills.
It must have been a fad for the aliens, not many of them showing up and/or making the news in quite some time.
