Tiling patterns and mosaics
Shapes that cover the plane. Periodic tessellations sit beside aperiodic tilings such as Penrose's and the Spectre, which never repeat, along with Truchet tiles, azulejos and Islamic strapwork.

What each one draws
Azulejo Rosettes
Scalloped flowers and curved diamonds grow from a repeating ornamental field. Nested ink lines give each tile a delicately engraved rhythm.
Woven Stars
Interlaced square ribbons form eight-pointed stars. Fine parallel strands carry a quiet pulse through alternating over-and-under crossings.
Diamond Relief
Fine ruled facets turn a tiled surface into a field of raised diamonds. Peaks rise, flatten and invert in a slow travelling wave.
Tile Drift
A field of ornamental tiles gathers into a fluid swirl, then settles back into symmetry. Move its centre to pull the geometry across the page.
Voronoi Flow
A cellular engraving: continuous currents pass through irregular Voronoi islands, separated by fine channels of open space.
Truchet Tiles
A square grid of quarter-circle pairs. Each tile flips by seed, so the sheet reads as one continuous maze of arcs.
Tumbling Blocks
A rhombille tiling: each hexagon is three rhombi, and the sheet reads as a stack of cubes.
Penrose Tiles
Kites and darts that cover the plane without ever repeating. Five-fold symmetry, golden-ratio edges, and no translational grid.
Hat Tile
A 13-sided polykite, the hat, that tiles the plane but never periodically. The first aperiodic monotile; Spectre later dropped the reflections.
Triangular Mosaic
A tessellation of equilateral triangles. Fill is the chance a face is inked rather than outlined.
Voronoi Cells
Sites from the seed, cells from the nearest-site rule. Some cells fill with copies of themselves, each ring an even step inside the last, like the rings of a contour map.
Hex Mosaic
A pointy-top hex grid. Fill is the chance a cell is inked rather than outlined.
Delaunay Mesh
The dual of Voronoi: every site joins its neighbours into triangles. Same seed and site count as Voronoi Cells gives the matching mesh.
Hex Truchet
Each hex picks one of two arc orientations. Adjacent edge midpoints join with 120° arcs so paths continue across the honeycomb.
Dovetail Course
Pins and tails along a seam: the planar ancestor of the universal joint. Flare is how hard the lock bites; columns is how many keys fit the run.
Star Rosettes
Islamic star patterns drawn the way the craftsmen did: lines leave the midpoint of every tile edge at one fixed angle and run until they meet. One slider changes the order of every star at once.
Decagonal Strapwork
Ten-fold star patterns on a tiling that never repeats. Two rhombus shapes carry the same strapwork rule as the periodic panels, but nothing about the arrangement comes back around.
Poincaré Disk
Every tile here is the same size. The whole infinite hyperbolic plane is drawn inside one circle, and the rim is infinitely far away, so the tiles appear to shrink as they approach it.
Multi-scale Truchet
Truchet's tiles, but each square may break into four smaller ones before it decides which way to turn. Arcs still meet at every edge midpoint, so coarse and fine areas join without a break.
Café Wall
Offset rows of blocks divided by thin mortar. Every row is exactly horizontal, and almost nobody sees them that way.
Scintillating Grid
Pale bars with a disc at every crossing. Dark spots appear in the discs you are not looking at, and never in the one you are.
Peripheral Drift
Nothing here moves. Each band runs dark to light the same way round, and the field creeps sideways whenever you look past it.
Necker Lattice
A field of wireframe cubes with nothing to say which face is nearer. Stare, and the whole field turns inside out at once.
Coffered Vault
A ceiling of sunk panels. Every recess is cut the same way, and the four sides of each take their own tone.
Tiled Floor
A chequered pavement running to the horizon. Every tile is square and no two are drawn the same shape.
Corrugation
Ruled lines that crowd where the sheet turns away and open where it faces you. Nothing is shaded; the spacing does all of it.
Hitomezashi
Running stitches along every row and column, each starting a half step in or not. The boxes and crosses that appear were never stitched.
Quasicrystal
Five or seven flat waves laid over one another at equal angles. Order everywhere, and the same patch never twice.
Dot Relief
One dot per cell, sized by a surface nobody drew. The grid is dead flat and the sheet rolls like beaten metal.
Basket Weave
Pairs of planks laid at right angles, turn and turn about. Flat on the page, and it will not stop going over and under.
Flower of Life
Circles of one size, each through the centres of its neighbours. Every petal, lens and six-pointed star in it is an accident of the overlap.
Celtic Plait
Two families of bands crossing on the diagonal, each one over, then under, without exception. No band ever ends.
Chevron Field
Bands of zigzag, every one the same and every other one a shade apart. The eye reads the pairs as ridges and folds the sheet.
Truchet Triangles
The original Truchet tile: a square cut on its diagonal, one half dark. Four turns of it, arranged by rule, give diamonds, chevrons and pinwheels.
Turing Pattern
Two chemicals, one spreading faster than the other, settle into spots, mazes or coral from an almost uniform start. No edge anywhere, so it repeats forever.
Seigaiha
Fans of concentric arcs in overlapping rows, each row laid over the last. Only the top of every fan survives, and the field turns into swell.
Bauhaus Blocks
Squares that round off some corners and keep others. Drops, leaves, arches and circles fall out of one choice per corner, set in a strict grid.
Pythagoras
A right triangle with a square on each side. Count the cells: the two smaller squares together hold exactly as many as the largest.
Heesch Numbers
A shape that cannot tile the plane, surrounded by rings of its own copies until no further ring will close. The count of rings is its Heesch number.
Spectre
A single tile that covers the plane without ever repeating, using copies that are only turned, never flipped. Bend its edges and it cannot be flipped at all.
Coxeter Frieze
Rows of whole numbers held between two rows of 1s, every diamond of four obeying one rule. Each such frieze comes from a polygon cut into triangles, drawn above it.
Stomachion
Archimedes' square of fourteen pieces, every corner on a 12 × 12 grid. In motion it comes apart, turns, and closes up again.
Pinwheel
One right triangle, legs one and two, cut again and again into five smaller copies of itself. Its tiles end up pointing in infinitely many directions.
Interlock
A plain grid of squares whose shared edges bend across the sheet until the tiles lock together like creatures. However far they bend, every tile still fits its neighbours exactly.
Bloom
A polygon ringed with Yoshimura creases that folds from a flat sheet through a bowl to a flat stack the size of its centre, like a flower closing.
Aztec Diamond
A diamond of squares covered by dominoes, chosen fairly from every way to do it, drawn as the paths hidden in it. Outside a circle everything freezes into straight lines; inside it the paths wander like ridges.
Moser Spindle
Seven points and eleven edges, every edge one unit long, that three colours cannot colour. So a plane coloured to keep points one apart different needs four colours at least; seven are enough.
Cairo Tiling
Pentagons laid like paving, four ways round, two by two into hexagons. Slide the bar and the whole floor shifts from squares through equal-sided pentagons and back.
Asanoha
The Japanese hemp-leaf pattern: a grid of triangles with every centre joined to its corners. Drawn as wooden kumiko, it opens into pinwheels.
Spirolaterals
Walk one step, turn; two steps, turn; and so on up to n, then start again. Most walks come home, drawing knots and stars from one simple rule.
Archimedean Tilings
Only eleven ways exist to tile a floor with regular polygons so that every corner looks the same. Each is named by the shapes round a corner: 4.8.8 is a square and two octagons.
Squared Squares
Cut a square into smaller squares. Let the sizes repeat and you have a patchwork quilt; make every one different and you have one of the hardest puzzles in geometry.
Mod Tables
A times table where every answer is swapped for its remainder. Hatch each remainder at its own angle and the table weaves itself into a symmetric quilt.
