Nearly a year ago, local photographer Jessica Atnip hatched an idea for a revolution.This isn’t the type of revolution that overthrows the government but one that centers on art and gives DeKalb County’s teenagers an alternative in a small community where sports rules.The result is an organization named Art Revolution that offers teenagers in grades 7-12 nine-week courses on different art forms. With the large artist community in DeKalb County, the group has been able to pull together a wide variety of artists to teach classes.This Saturday from 7-9 p.m., after months of work, Art Revolution is officially unveiling the plans with a festive event at the 303 Building in downtown Smithville. More than 100 tickets have been sold for the event.
