I met the guy who thought of the idea, Ian Green. He bought the stone in North America, paid for it to get carved, etc. He's pretty enthusiastic about it. A real businessman, but nice. He lives in Bendigo, Australia, and the dana raised by the statue tour goes towards building the stupa at Thubten Shedrup Ling Monastery http://www.tslmonastery.org
The stupa is INCREDIBLE and HUGE. When I stayed at the monastery the builders were busy, so I couldn't go up it. But one evening after they went home I sneaked under the gate (at the subtle suggestion of the abbot, Venerable Gyatso) climbed the stupa, and watched the sun set from the sixth floor. It's going to be twice as tall once they put the top pointy bits and round bits on there. Remarkable.
