Os Gemeos (Portuguese for The Twins) is the name the Brazilian graffiti artist twins go by in the art world. They usually create pieces on a grand scale, featuring yellow-skinned characters. Their subjects range from family portraits to social and political circumstances, and even Brazilian folklore. 

Os Gemeos' latest work is a mural at Boston's Rose Fitzgerald Kennedy Greenway at Dewey Square. It's painted on a Big Dig venilation building.

It draws criticsm from a diverse group of people, who leave comments such as "terrorist," "raghead," "wife of a terrorist," "gay ninja," or that it is, "...seriously poor taste." And that's just some of the tamer ones.

It just might be as Johnny Dow comments, a "rorschach test for idiots and racists."
