These pieces are part of Bruce Munro’s Sonoran Light exhibit at the Desert Botanical Garden comprised of hundreds of miles of glowing fiber optics and many light-based installations.
30,000 individual spheres of light are on the butte and surrounding area. The work involved in assembling this installation is remarkable in itself (click to enlarge for more detail).
This dome is made of recycled plastic water bottles as is another exhibit called Water Towers (my photos weren’t good as these are all handheld but you can see a photo of it here).
We went on a Saturday night, not the best night as it was jam-packed with people. It was interesting to see but, honestly, I prefer the garden in its natural beauty and wasn’t that thrilled. I was glad members get in for free.
To me, this is much prettier (also from the Desert Botanical Garden):
It did provide me with a bird-free post, though, which I like to throw in every now and then.
