It’s been a while since we’ve had a slideshow, and I thought that the continuing heat wave might create the need for something cool. (Aside from the regular coolness that is always present on the GMC, of course.) I did something similar on Memorial Day, but in that case the pictures were of snow sculptures. This time around, we have ice sculptures — and not just any ice sculptures, but those that show the inventive use of color. In most cases, the colors come from the way they’re lighted, but there are also a lot of people experimenting with using colors in the ice itself.
