STRUCTURE INDEX / 13

Start with a pattern.

Pick the one that catches your eye. Shape and color are yours to change.

One blue, one cream. A different rule in every pattern.

Truchet

Quarter-circle tiles join into loops and meanders. Small changes in orientation create a larger flow.

Scattered points divide the plane into cells. Adjust their spacing and irregularity to move from an ordered mesh to an organic texture.

Dots on concentric circles become sweeping waves. Change the spacing and twist to move from gentle swells to a fine weave.

Twist a ribbon made of dots. Where the rows overlap, they grow darker and give the flat image a sense of depth.

Rows of dots bend like a rippling sheet of cloth. Light and surface tilt give the pattern its soft shading.

Turn a regular grid into a net of curves. The lines bend while keeping their crossing angles.

Soft bands that suggest water or terrain. Layer a few waves to draw tones like contour lines.

Rotate and stretch rows of orderly dots. A regular grid begins to move like the sag of a fabric.

A tiny offset becomes a large rhythm. Adjust the spacing and angle of two grids to explore their interference.

Ordered, but never quite repeating. Waves from five or seven directions meet in a pattern that resembles a crystal.

Add smooth waves together and a small ripple remains near each sharp edge. Rows of dots make that persistent ringing visible.

Arcs of tone suggest light on the bottom of a pool. A distorted field forms bands that resemble gathered light.

Spots grow, connect and become a maze. Two reacting and diffusing components create organic patterns. This one takes a little longer to compute.
