It is a problem in structure as the back sides of the boulders are round. Pretty colors though. Lots of sparkle. Red, blue, pink, black, yellow, green, brown. Visually though I don't suspect that it would betray this falling out flaw to the unsuspecting visitor until a stone fell out. It is one of the reasons that I have for a long time been interested in glass fiber reinforced concretes/mortars. But I also know that once the dome heats up and starts to twist that it is inevitable that at some unknown point-in-time that a stone would pop out. Bonk! I believe some structures are better imagined than built. ][<en -- To terminate puerile preservation prattling among pals and the uncoffee-ed, or to change your settings, go to: <http://listserv.icors.org/archives/bullamanka-pinheads.html>
