All work, some play: how hackathons are transforming China’s tech industry
Makeblock and other start-ups are using creative get-togethers not only to discover promising new tech, but to break free from the kind of stuffy, top-down traditional corporate culture that holds back progress

The note on the tech company’s front door was quite clear: “Use your staff card, please. Don’t knock. It is not nice to disturb others’ work.”
But on this particular day, the normally staid and hushed workspace was roaring with music and exclamations loud enough to make windows shake.
“Nice shot!” one shouted. “Back! Back! Oh, no!” another screamed.
In this case, the kind of noise usually reserved for a soccer match between Liverpool and Manchester United was triggered by competing robots.
These machines, made of plastic, metal and tubes, moved gracefully in a play yard the size of two office tables, grabbing balls on the ground and throwing them to hit bowling pins defended by their mechanical rivals.
