'Zodiac Heads' Take Over Boston's Rose Kennedy Greenway

BOSTON (CBS) -- Animals are taking over the Rose Kennedy Greenway.

Twelve bronze animal heads have been installed around the Rings Fountain between Central and Milk streets.

It's part of "The Zodiac Heads" series by acclaimed Chinese artist Ai Weiwei.

The sculptures stand 10 feet tall, and each weigh from 1,500 pounds to more than 2,100 pounds.

They are installed in the traditional Chinese Zodiac and will grace the Greenway until late October.
