The Barrios World Wide Web guitar competition is underway. Three finalists from Russia, China, and Jordan will participate in the championships on December 4th in Paraguay. I'm sharing two of the finalists' performances here. I didn't know how to link to videos by the third finalist, Chen Chuan, because his were presented in a different format.
When Eric Whitacre originally planned his Virtual Choir, he thought it might have 900 voices. But he ended up with a 2052-person choir!
P.S. I've posted Eric Whitacre's stuff before.
