A calming mesmerizing exhibit consisting of two pendulums one
supporting a phosphorescent screen with a ultra violet light emitting
diode mounted below and the other a simple rod with a ultra violet
light emitting diode imbedded in its tip. The viewer is free to
cause the lower bed to swing around or any which way as well as to
nudge the hanging rod to swing back and forth or around and around.
The variations of design and every-changing relative motion, as
momentarily captured on the glowing screen, are endless.
