On an autumn night in 2009, I experienced a version of this piece installed in a stone barn in rural France. The evening was moonless and cold; I stood with two friends inside the piece for the better part of an hour, as our eyes adjusted to almost total darkness, before any of us could begin to see one another. It was the definition of a liminal, or barely perceptible, experience. Eric Orr, who died in 1998, was involved with Zen Buddhism and considered these pieces to be spaces for meditation. Experiencing them as intended requires the visitor to focus quietly on the mechanics of their own perception.
Picture a blind man probing his way with a cane. While he is alert to the feelings in the hand holding the cane, the crucial distinction may be defined by saying that these feelings are not watched in themselves, but that he watches something else by way of them, that is, by keeping aware of them. He has a subsidiary awareness of the feelings in his hand, feelings which are merged into a focal awareness at the end of the cane, constituting two kinds of awareness that are mutually exclusive — "from awareness" and "focal awareness".
There is here a particularly interesting phenomenal transformation. The sensations of the cane on his hand (the surface of the cane as it touches the palm of his hand, etc.) are lost. Instead, he feels the end of the cane as it touches an object...If our blind man shifts his attention from the tip of his cane to his hand, the meaning on the end of the cane disappears.
