Just discovered this while wilfing around on YouTube. Posted in 2005 so probably everybody else but me has already seen it, but despite low respolution and awful audio quality it’s just stunning.
The YouTube posting looks like a copy of a copy and gives no credits – who made the robots, who created the dance, or where it all took place. Seems really odd that the presentation is obviously taking place in a room full of people, yet nobody applauds at the end. The language being spoken is Japanses – maybe applause is forbidden by some weird form of business etiquette.
