Final Buckyball doodle

MOUNTAIN VIEW, Calif.--We've all seen them: the so-dubbed Google "Doodles," the special versions of the company's logo that celebrate holidays and other occasions. But how do the doodles come to be? It turns out that the search giant has a team of "Doodlers."

CNET reporter Daniel Terdiman visited with the Doodle team last month to discuss the creation process and to see several upcoming logos.

One of the doodles in progress was this one, which celebrates the 25th anniversary of the discovery of fullerene, the so-called "Buckyball." It was created by team member Jennifer Hom and was published Saturday.
