Artistic abstraction, with its pleasing focus on form and color, is well-suited to summer's easygoing nature. As summer debuts, there's a fair amount of abstract exhibits going down around Atlanta. In Decatur, Atlanta-based artists ALEX BREWER and IVAN REYES reanimate the form with their often witty, kinetic forms at Function Gallery. Though Brewer's and Reyes' show opened May 25, the same weekend as the 18th annual Decatur Arts Festival, the exhibit continues through Mon., JUNE 25. Free. Mon.-Fri., 9 a.m.-5:30 p.m. 508 E. Howard Ave., Decatur. 404-524-3075. www.functionatl.com.
