Public graffiti walls carry decades of hidden cultural and political history within their layers of spray paint. SKRFF_ology began as an investigative excavation of the public walls around Vienna. Treating the wall like both an archeological site and a sgraffito sculpture, the artists activate the layers of the past with stopmotion animation. The resulting animation invites the viewer into an overwhelming sensory experience that can be viewed from an aesthetic frame of reference or a philosophical one. Unraveling the past seems a necessary endeavor (both as society and as individuals) to avoid making the same mistakes over and over again, but the act of digging in raises the question of whether the past can ever be remembered clearly in all its complexity.
