Hi, Summer,
I was at the California Science Center in Los Angeles a couple of weeks ago
with my family and saw what you're probably looking for in their exhibit on
light. The exhibit includes a set of prisms, mirrors, and lenses and allows
the participant to direct light from a source to the base of a bundle of
fiber optic strands. When everything is lined up just right, the light
shines through the ends of the fibrer bundle, which is splayed out like a
large fountain at the top, about 5 - 6 feet tall. I was just a visitor, so
I can't tell you a source, but I'm sure they can.
