Artist Ara Peterson fuses technology and craft to make his abstract geometric artworks. Working across mediums—paintings, prints, sculpture, installation, video—Peterson creates optical illusions with hyper-saturated, psychedelic coloring and a physicality that points to his labor intensive process. For his 2009 Ratio 3 show Turns into Stone, Peterson made his retro wall reliefs by feeding complex wave formations into a computer that laser-cuts the slats that he then assembles into eye-boggling designs. Also included in this exhibition were a series of backgammon boards that the artist produced with his father. These pieces demonstrate the same colorful geometry for which he is known, but the patterns are actually rooted in ceramics and memories from his family history. Peterson's work proves that abstract geometry can be personal and intimate.
