LITTLE SUNSHINE

"Miniature structure and optics combine as the sturdy black stand holds the facetted cylinder of clear acrylic.  This crystal form spins on delicate points of contact.  A reflected laser beam triggers a magnetic pulse that repels tiny magnetic disks on the many sides of the cylinder, causing it to turn, and through the clear acrylic appear multiple eclipsed suns with squiggly rays highlighted by the red light, which pools below as on a body of water: magical sunsets." - Clark Poling, 2014. 

Little Sunshine combines optics by Michael Rudnick with electro-mechanics by Norman Tuck.
