| art description | A voice coil vibrates linearly at roughly 50 Hz, at the
resonance frequency of the flexure mounts on which it travels. This
shakes an extension spring, tuned to match the voice coil frequency
for one of its resonant modes. 12 banks of 165 LEDs each strobe behind
the spring, through a translucent acrylic window, matching the
vibrational frequency and running at roughly 1\% duty cycle, allowing
the viewer to see the spring in a suspended/frozen state. Changing the
relative phase between the 12 banks of LEDs creates a positioning
system for each segment of the spring, which allows the spring to be
broken into segments and seemingly moved independently of the physics
governing the original vibration. Various effects are explored from
this initial thought.

| art proposal | An experiment with matched mechanical, electrical, and visual resonances,
using a spring and light. This is not a computer simulation. A spring is
vibrating faster than humans can perceive, and is being strobed at a rate
faster than a human can perceive, but in such a way as to simulate much
slower motion. Creative strobing allows multiple effects such as splitting the
spring into constituent parts [which does not actually happen!].

This shakes an extension spring, tuned to match the voice coil frequency for
one of its resonant modes. 12 banks of 165 LEDs each strobe behind the
spring, through a translucent acrylic window, matching the vibrational
frequency and running at roughly 60Hz, allowing the viewer to see the spring
in a suspended/frozen state. Changing the relative phase between the 12
banks of LEDs creates a positioning system for each segment of the spring,
which allows the spring to be broken into segments and seemingly moved
independently of the physics governing the original vibration. Various effects
