Your child can learn to draw anything…starting from a butt. This Saturday, The SoHo Gallery for Digital Art (138 Sullivan Street) is launching “Everything Butt Art at the ZOO,” which is an interactive activity book and iPad app that teaches children the core principles of step-by-step drawing… with a twist…every drawing originates from the outline of a butt. Saturday’s launch party from 2 to 5pm will include an art exhibit, story time & drawing demonstrations, interactive activity stations and balloon art. The event is free and suitable for all ages.
