A giant plain of circles and diamonds. Tap a circle to set a tile — where you tap inside it points the tail.
Drag to lay a run of tiles along the stroke. Tap a laid tile to recolour it; hold and drag its circle to move it, its diamond to swing the tail.
Right-drag or the hand moves the plain; pinch or scroll zooms. The painting saves itself as you go.
The lone shape button switches the brush — nuna tile, bare circle, bare diamond. Square = circle + diamond.
The prismatic nuna rolls a surprise palette. The three lines hold every dial — brushes, palettes and exports.
