entropybrush for iPhone and iPad

entropybrush is a physics-based oil painting studio — the paint is actually simulated, so strokes carry a load, wet paint flows, and thick paint builds real impasto relief you can light and tilt in 3D.

Getting started

• Paint — pick a color from the palette, then drag one finger on the canvas. A tap leaves a single dab.
• Move the canvas — use two fingers to pan and pinch to zoom.
• Tilt in 3D — drag the circular orbit control (top-right) to rotate the canvas and see the paint's relief. You can orbit with one hand while you paint with the other.
• Spin art — turn on spin to fling wet paint outward into centrifugal spirals.
• Light & drips — adjust the lighting to rake across the texture, or tilt the canvas to let loaded paint run.
• Export — save your work as an image, or as a 3D model of the painted surface.
