Not only interesting in its own right, but I'm quite struck by the fact that this comes from a Chinese university.
We've long become used to the fact that the West has lost much of its earlier technical leadership over China. But there's still an assumption that we have the edge in "creative play" of the kind that will stimulate the next generation of products and applications.
