This is an amazing video of a Virtual Choir directed by composer Eric Whitacre. They are singing his music, Lux Aurumque. The virtual choir is made up of 185 voices, was recorded using 243 tracks, by singers in 12 different countries.

Translation of the latin text:

Light and Gold
Light, warm, and heavy/loaded/pregnant/deep/dignified*
Pure as if gold.
They sing/prophesy.

*’Gravis que’ is actually written and said as one word, Gravisque, meaning “and [definition]”. There are so many words listed because it actually means all of those, in a poetic sense that is difficult to capture in one word in English.
