Plaster, by numbers

Every texture on this site — the cream plaster, the concrete, the ink wall — was made with a short script rather than a camera. That way nobody else owns them, and they can be redrawn at any size.

The trick is restraint. Real plaster is mostly calm, with a few marks. Version one was all marks and looked like porridge. Version two added trowel sweeps and cracks at two per cent opacity, and suddenly it was a wall.

I still want to photograph a real wall — the one behind the car park has perfect damp — and swap it in one day.
