Ok, not exactly what I expected but actually cooler.  “Largest Kaleidoscope”, I am thinking a big telescope looking thingy that you hold and turn to get the shapes.  Nope.  This one actually resides in an old silo – yeah, big.  We are “seated” in a viewing room.  They turn down the lights.  Accompanied by a great story reminding us that we, actually all things, are born of star dust; they animate the kaleidoscope so that shapes form, combine, disappear, and reform as a new image on the ceiling of the room. I loved it and found it hard to resist buying a more reasonably sized one to create the show for myself when the mood presents itself.  The kaleidostore had stuff to buy of course and some cool exhibits.  My favorite was a mirrored and decorated chamber that when you stick your head in the images seem to go on forever reflection in reflection in reflection.  Amazing.
