Twisting pattern described by rotating subjects along a line in space
Several subjects located at various distances from the center of a turntable spinning in
front of a home-made "streak" camera that looks at a single line in space over time,
describe sinusoidal traces whose slope at any given time is a function of the distance
from the center of the turntable to their location on the turntable surface. The steeper
the line the farther the object is from the turntable center. In this case the photograph
was turned sideways and therefore time is displayed along the horizontal axis.
