I was inspired to try to capture the mystery of stonehenge.
The scene itself is not technically complex, but I still believe the effect is striking.

The viewer is positioned within the first ring of stones viewing the center dais.
A (very) large nearly perfectly reflective sphere is positioned in the distance such that
the viewer sees a fisheye perspective reflection of the inner stones and the outer
encircling ring. A point light in positioned atop the center dais to cast shadows through
the arches of the inner circle, illuminating the stones further out.

The scene perhaps wasn't exactly what I was going for, but it's still pretty spiffy.
