It was designed by the same people who do the Great Jack-o-Lantern Blaze each year, except that you walk through the grounds of Washington Irving's estate instead of the grounds of a different historic Hudson Valley estate. Woot. This really was very cool, though. I'm not doing it justice.
The general theme of the light display was, essentially, "What did Rip Van Winkle dream about when he was asleep for twenty years?"
So here's Rip.
There's a line in the story about his how whiskers became the stream, hence the fish.
More whiskers. The other theme was "Winter."
And the OTHER theme was "recycled goods" and "ecological sustainability," brought to you by Entergy, the operators of your friendly neighborhood nuclear power plant! (I am not making that up.)
The "icicles" were made out of reused waterbottles.
As you got to the end of Rip's long, wintry dream, "flowers" were starting to bloom. The flowers are made out of re-used milk jugs.
And because of the eco-friendly design and use of LED lights, the entire thing used up less power than it takes to runa hairdryer. HOW COOL IS THAT?!?
