“Without vitamin C,” Anthony writes, “we cannot produce collagen, an essential component of bones, cartilage, tendons and other connective tissues. Collagen binds our wounds, but that binding is replaced continually throughout our lives. Thus in advanced scurvy”—reached when the body has gone too long without vitamin C—“old wounds long thought healed will magically, painfully reappear.”
In a sense, there is no such thing as healing. From paper cuts to surgical scars, our bodies are catalogues of wounds: imperfectly locked doors quietly waiting, sooner or later, to spring back open.

New milling techniques applied to glass and plexiglass panels could be used to “create windows that are also cryptic projectors, summoning ghostly images from sunlight.”
[Pauly and Bompas] hope that the technique will be used in architectural design, to create windows that mould sunlight and throw images or patterns onto walls or floors,” which, if timed, milled, and manipulated just right, could produce a slowly animated sequence of images being projected by an otherwise empty window during different times of day.
For others, perhaps especially those artists who worked with light and transparency and were involved in the birth of the Light and Space Movement, an immaculate surface is a prerequisite. Helen Pashgian explained this very clearly:
“On any of these works, if there is a scratch... that’s all you see. The point of it is not the finish at all – the point is being able to interact with the piece, whether it is inside or outside, to see into it, to see through it, to relate to it in those ways. But that’s why we need to deal with the finish, so we can deal with the piece on a much deeper level”.
The importance of a pristine surface calls for a very low tolerance to damage by the artists. The feeling is shared by Larry Bell:
“I don’t want you to see stains on the glass. I don’t want you to see fingerprints on the glass... I don’t want you to see anything except the light that’s reflected, absorbed, or transmitted”
