Dance of a 1000 Hands

My mom sent me this video recently. Here is the info from the accompanying email:

There is an awesome dance, called the Thousand-Hand Guanyin, which is
making the rounds across the net. Considering the tight coordination
required, their accomplishment is nothing short of amazing. All 21 of
the dancers are complete deaf-mutes. Relying only on signals from
trainers at the four corners of the stage, these extraordinary dancers
deliver a visual spectacle that is at once intricate and stirring.

Its first major international debut was in Athens last year at the
closing ceremonies for the 2004 Paralympics. But it had long been in
the repertoire of the Chinese Disabled People's Performing Art Troupe
and had traveled to more than 40 countries.

Its lead dancer is 29 year old Tai Lihua, who has a BA from the Hubei
Fine Arts Institute. The video was recorded in Beijing during the
Spring Festival this year.
