And quite beautiful.
One has to wonder if a group of guys are doing ALL of these circles, ....who is the main designer (because he most certainly has an imagination that rivals Picasso on mathematics).
And he must have a well-funded, well rested team behind him that NEVER makes a mistake, gets caught or does them half-way finished. They also must be able to fly around the world and put them down in remote locations in over 15 countries, so they are a well funded, stealthy lot.
And they must be smarter than the greatest of modern day engineers to design them, lay them out and execute them to an exceeding detail that our engineers would need DAYS to lay down. At considerable cost too.
After over 20 years of these patterns, they should be FAMOUS and on National Geographic or heading up the arts internationally. What a waste of talent.
Not.
