Nowadays? Y'mean alien signalling is evolving? Scary.
A couple of guys in England got a lot of play two or three years back when they confessed to several they had done. Some of their work was quite elaborate. Perhaps someone here can outline the technique involved ....
I could tell you, but then my alien masters would...let's just say I'd "disappear". ;)
It's not nearly as hard as you might think - like I said in #55, the equipment you'd need is strictly bare bones stuff...
If you're referring to the "Circle Makers", previously known as "Team Satan", although they may have created somewhat elaborate formations, they've never been able to duplicate the symmetry, mathmatical and geometric precision, or the "bending effect" found in actual crop circle formations. Also lacking is the celluar changes, background EM/RF emissions, and elevated radiation levels.
In fact, in a attempt to create an elaborate formation, they spent DAYS in New Zealand in creating one in the DAY. Again, it lacked symmetry and geometric precision, as well as the other aforementioned characteristics.
