Each of these clever models balances in an interesting and curious way and they all make use of small coins as weights. The beautifully painted and colorful models include two kinds of parrot, each on its own stand, a cockatiel, a pair of Toucans and three butterflies each of which settles on a pyramid of its own. Not only are these models delightful and charming to make but they have the extra fascination of their unexpected equilibriums.
