Olympic Boxing?

On a completely different note, I saw this photo of a performance in the opening ceremony of the Olympics. Quite frankly, I wasn't sure what to make of it or the caption, "Artists underneath movable boxes perform during the Opening Ceremony for the Beijing 2008 Olympic Games at the National Stadium on August 8, 2008 in Beijing, China." I've looked around these pages on the official Beijing 2008 site and finally found it... any guesses? Highlight the black box below with your mouse to reveal the answer.

It's a performance celebrating the Chinese invention of moveable type (see 12.3 and 12.4 under Performance on the link above).
