Building on the dual matte/glossy finish concept used in its PixelSkin HD case, Speck's new GeoMetric ($30) for iPhone 4 features a rear design with different textures and different elevations, using triangles to create interesting gem-like bulge points. The rest of the case's sides, top, bottom, and front are matte finished. Only one color -- black -- is currently available, and sold without screen protection.
