"24-Hour TV" is a national telethon held every year in Japan to raise money for charities. From this year's telethon—a portrayal of the "Senju Kannon," the thousand-armed goddess of mercy.
The theme of the segment in which this particular 6-minute performance was given was "silent performances." No digital effects are used, just clever choreography and camerawork.
UPDATE: It turns out there is a reason the performances were silent—they were by deaf performers. The Kannon piece was performed by the China Disabled Persons' Performing Art Troupe. What's more, this performance on the telethon was such a hit on TV that the troupe is currently on tour in Japan.
