Linda Graham has a background in ceramics, which she exhibited way back in the 1980s, but in the past few years she's discovered digital art -- which really couldn't be more different.
In the impressive Linda Graham: Personal Perceptions at Hinterland, the artist has designed a set of curved walls in clear acrylic sheeting that are set up in the darkened room. Some of the acrylic has a yellow cast, some of it green.
A video projector using an altered 3-D design program, SketchUp, projects non-objective shapes against and through the acrylic sheets. These projected shapes are in constant movement, and as they run across the curved surfaces of the acrylic, they change, and as they cross the different colors, the light itself changes.
Interestingly, it's visually substantial, but pretty insubstantial from a physical standpoint.
