I think they used Spirographs, with really big wheels.

I've seen a video of people making these crop circles. Was pretty interesting. They use some very simple techniques though, long pieces of wood to flatten a large area infront of them as they walk along in patterns.

Were these "people" tall and kind of grayish looking?

Now you're blaming Bruce Forsyth?!

Time to 'fess up? OK, you found me. I made that round one.

Yes, the called them geometric chucks in those days:

I want to know what they redacted.

That picture is as good as porn to some Dwellers.

The electric motor attached to it on the side there looks out of place.

I used to date Geometric Chuck. He was such a square. Always had me running around in circles trying to figure out his angle. One night, I cornered him and he confessed: he was involved in a love triangle with a woman with a great figure, which was not congruent to my long-term goals. The proof was right in front of me.

Oh yeah, he's still got the knickers you left behind. ;)

That is just ... twisted.

:lol2:

Yeah, you can see how long ago it was, when my big fat ass could still fit in that particular pair of mobius undies.

I like that crop circle in the far right column that actually looks like a sink hole! (concentric circles)

That's the funniest thing I've seen in quite a while. I don't get out much though. :)
