Dance, dance, evolution is gamers' code for fun

It was Christmas Eve revelry, indeed. The dancing kind. A new kind of dancing in a Beijing arcade on Dec 24, to be precise.

The arcade was crowded by people who'd come to see gamers take turns onstage - or, more precisely, on a 3.75-square-meter video-game footboard.
