I returned to my pendulum today. This is the very center of the sand affected by the pendulum’s travels. It always makes this nice little box in the center, reminding me of a very, very small stadium, constructed of sand.

I photographed this with my Canon 7D and MP-E 65/2.8 macro lens, edited it in Photoshop CS4E, and used Nik Silver Efex Pro to both convert it to black and white, as well as apply some bluing to the sand.
