We posted a back-to-school guide to this fall's best lectures and classes the other week. Here's another one to add to the mix if you're feeling particularly wild and crazy: monthly toy modification classes at SOMA's 1AM Gallery. Their September classes have sold out, but their next class is coming up quickly on October 23rd, just in time to get in the spirit of Halloween! Sign up here now, because spaces go fast. Customize toys provided by KidRobot any which way your mood dictates. You can paint, hack and glue your way to a cute (or totally creepy, your preference) toy of your very own. Sign up for the 1-session beginners' class here, which is taught by Lily Black.

1AM (which stands for First Amendment) Gallery is not only an urban and street art gallery, but a forum dedicated to casting a positive light on these misunderstood forms of art by teaching people the history and culture behind street art. 1AM also offers cool classes in stenciling, sketching graffiti letters, and mural production.
