It's been said the origin of the word circle was originally Seer Call (cir -cle) = calling in all seers, which is what the druids and celtics did when they needed a problem solved. Then the seers would stand in a circle, hold hands and meditate.
Perhaps whoever is making these lovely and tantalizing symbols are calling in all seers. considered yourself called!
P.S. Any thoughts on the one button that seems to be pushed down - what would that relate to on a computer screen or perhaps even a TV?
