This particular windchime is replete with Tibetan symbols:
Wheel of the Dharma
Endless knot of Eternity
Sino-Tibetan Zodiac, Trigrams and Magic Square
Hanging bells are less common in Tibet than the Tibetan handbells used in ritual. Hung outside, one can imagine the mantras and ideas contained within the symbols permeating the landscape as the bell is rung by the wind. The sound of the windchime serves as the divine voice.
