Art class for tots and toddlers?

Can anyone recommend a class for tots? Maybe something that my 3 yo and I can do together (like a mommy and me)? If there's some kind of an art class out there, that would be really great because I love to do art and my little guy loves to scribble and paint. I live in Oakland but am willing to travel within the East Bay if there's something good out there. My kid goes to preschool part time so we have some free mornings to do stuff. Thanks!
