Though shes still just a pup, recent Atlanta College of Art grad HEIDI GELDHAUSER really goes out on a limb. Her thesis exhibition, Fluff, at ACAs Gallery 100, featured an installation of wedding cake and plates that invited her audience to participate in the art experience, which provoked an unexpected reaction from gallery-goers. Some were content to just eat cake, but in a troubling turn, others vandalized the installation and smashed dozens of plates. Geldhausers implicit question of just what constitutes art was clearly provocative, even threatening to some. In a concurrent show, The Future Perfect featuring work by graduating ACA students, Geldhauser challenged convention yet again by making a wonderfully clever and labor-intensive work that suggested the Sistine Chapel done by a fourth-grader. Clearly ambitious, Geldhauser is currently at work on a follow-up work addressing myth and fantasy.
