A few weeks ago, our homeschool group went on a field trip to the Indianapolis Children's Museum. We'd been there a few years ago, but they have a new exhibit that was absolutely amazing.
"Fireworks of Glass": a four story tower of blown glass by artist Dale Chihuly. It is built on a glass floor, and what you see from underneath the tower is almost more impressive.
The entire floor/ceiling is layered with hundreds and hundreds of pieces of blown glass in an array of colors and shapes. With the lighting behind the glass, the effect is breathtaking. I could have stayed there all day looking at it. Very, very cool.
I took many more pictures than these, but you get the idea. If you get the chance, you should go.
