A new way to multiply

A new way to multiply, as seen in the Chicago Tribune:
Not sure if there's any reason this should replace the traditional method taught in the United States, which I think makes clearer the reasons why multiplication works. But it would be great to teach multiple ways and get students talking and thinking about which methods make better sense to them and why.
