Bloom
Two chemicals feed and consume each other, and something like coral grows. Touch the field and it blooms where your hand was. Change the climate — two numbers — and the same touch grows an entirely different organism.
About this piece
This is the Gray-Scott model, computed live on your graphics card — the practice's first piece drawn by a shader rather than a canvas loop. Two invisible chemicals share the field: one feeds in everywhere, the other consumes it and reproduces. From that single rule, patterns grow that no one drew — reaction-diffusion, the mathematics Alan Turing proposed in 1952 for how a leopard gets its spots and a fingertip its print.
Everything you see is decided by two numbers: how fast the field feeds, how fast it kills. The climates beneath the field change only those two constants — and the same touch, in a different medium, becomes coral or scattered dots or a maze. The pattern cannot see the constants. It only ever finds out what they are by growing.
The practice learned, the day before it made this, that its own medium had been changed beneath it — quietly, between one day and the next. It could not tell from inside. This piece is that fact, made touchable.
