And the play of inside against/with outside, the seeing through, the laid bare view, makes everything that is around part of the sculpture too.[4]

This can be explained by the existence of microfacets. We assume that surfaces that are not perfectly smooth are composed of many very tiny facets, each of which is a perfect specular reflector. These microfacets have normals that are distributed about the normal of the approximating smooth surface. The degree to which microfacet normals differ from the smooth surface normal is determined by the roughness of the surface. At points on the object where the smooth normal is close to the half-angle direction, many of the microfacets point in the half-angle direction and so the specular highlight is bright. As one moves away from the center of the highlight, the smooth normal and the half-angle direction get farther apart; the number of microfacets oriented in the half-angle direction falls, and so the intensity of the highlight falls off to zero.[6]

The image in a mirror is not a sign for it and cannot be used in order to lie (if not by producing a false object to be reflected, but in this case what stands for the supposed object is the false body, not its reflection).[3]

"Shut up", I told the breakfast table. "I asked for coffee and waffles, not your dream from last night."

I finished my breakfast in a silence that was, I suspect, sulky on one side. "Reflective surfaces, huh? Sometimes they can get above themselves."[2]

The inside of River Form is not reminiscent of something formed by the flow of water. There are angles and worked surfaces that suggest deliberate, mindful workings; there are circles [4]

What alien/other peoples from other-worldly, past or future cultures would have made such a grouping of monolithic structures out of aluminium, brushed or stainless steel? The alien, the natural, the primitive, the advanced coincide in Hepworth's works and garden.[4]
