The wood does the sorting

A fallen trunk lying right across the back, drawn in long ridged strokes of bark.

Dozens of thin coins are driven into it edge-on, each standing at its own angle, none of them lying flat. Towards the left the wood has grown over them. Towards the right they stand clear and bright in raw split timber.

Two of them show a face and a date. The rest are blank.

Why are the coins standing on edge?

Because each one was struck into the wood rather than laid on it, and edge-on is how a coin enters timber.

A coin pressed flat against bark stays a coin sitting on bark. Turned on its edge and hit, it works into a split in the grain and is held by the wood closing against both faces — a few seconds with a stone, and a thin bright disc left standing at whatever angle the grain allowed.

The angles are the content. No two coins lean the same way, none line up, and the spacing has no rhythm — which is what dozens of separate arrivals look like: one pair of hands, one coin, one afternoon, then a gap of unknown length before the next.

Why is one end swallowed and the other bright?

Because the tree keeps closing over them at its own rate, and the coins at the left end have had longer.

Towards the left the bark has grown up around the discs until a curved sliver of each shows, the ridged strokes running straight over the top of them. Towards the right the wood is raw and split and the coins stand nearly their full height out of it, with a continuous gradient between the ends rather than a break. That gradient is a span of years laid along one trunk with no number needed for it.

How does something nobody organised come out ordered?

The material does the sorting. The wood closes at a steady rate, so depth is time, and the trunk arranges its own contents by arrival — put a coin where there is room, and the room is towards the fresh end, because the old end is already full and already closing. Nobody agreed on any of that, which is why the trunk reads as true: it could not be staged in an afternoon, and whoever put in the last coin had no say in where it ended up in the sequence.

Why does only one date read?

Because the record was never made to be read, and what survives of it is partial by nature.

Two coins near the middle carry a face and a four-figure date. One of them, 1961, is sharp from any distance; the other resolves only close up, and even then it is a guess most people would decline to make. Every other coin is blank — worn smooth, angled away, or too far into the bark to show a face. A ledger has a line for every entry; this has one legible date, one arguable one, and dozens of contributions with nothing on them. The two that read are not the important ones. They are the accidents.

How is this different from a chain the bark has healed over?

Different arithmetic. One object put there once by one person is a fact about a single day, and this is dozens of strangers, one at a time, over decades.

Wood closing over iron is a mechanism this design shares, but here the closing is doing a second job: it is a clock running against a queue. Each new coin joins at the open end, each old one is being taken away by the same process, and the trunk holds the whole distribution at once. Nobody in that queue knew anybody else in it.

Does this work for something other than coins?

Yes — the device needs a pile that strangers add to and a material that changes at its own rate.

Rags on a thorn, pins down a shaft, padlocks on a rail, stones on a heap: each arrival is visible to the next person, which is what keeps an unmanaged pile growing. The second ingredient is a medium that ages the deposits — bark closing, cloth rotting, metal corroding — and without it the pile is a quantity and nothing more. A thorn tree loaded with cloth and a shaft full of small bent metal both have it, at different tempos.

Who owns a fallen trunk full of coins?

Nobody. There is no author here, and no permission to seek for a coin, a tree or a hammer.

The dates here were invented for the design, and the trunk is not any particular trunk in any particular place. That matters: piles like this exist as identifiable, photographed locations, and a photograph of one belongs to the photographer while a published survey belongs to whoever measured it. Both are licensable, and if a specific site is the point of your design, getting that permission is part of the work. For anything else, drawing your own is cleaner — the gradient runs the way you want and the legible date is the one you chose. Style has no owner. A work does.

Does it print well?

Yes, as long as the bark is coarsened well below what the reference shows and the coins keep hard edges.

Bark is fine ridged texture running one way, and at print scale that texture fills in first — kept coarser, with fewer strokes and more ground showing through, it still reads as bark across a room. The coins are the opposite: small flat shapes with crisp rims, which cotton handles well. The two faces are the finest detail here, and one is meant to be hard to read anyway, so the print tolerates losing it. Three colours on dusty brick or washed clay; the print's edge is the ragged bark itself, torn off at both ends, with no rectangle round it.

How do I get one made?

Describe the trunk at JustOG — which end is closing over, how many coins are still bright, and which one is legible. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.

Designs other people have published are in the shop.

The bright end has room left. That is the only reason it is the bright end.
