Interesting shot! At first glance it looked to be a plot of the zodiac with the planetary motions...a brief thought was maybe a magical spell, wicca or black magic, cast on the floor....I love pictures that give the mind room to wander! Great work!
Makes me think of ancient scientific texts with drawings of chemical compounds or metals. The bricks add to the age, the half seen people add dark mystery.
Do you know what does it mean?
