GeometriaA little room for wonder.

A circle becomes a flower. A rhythm becomes a curve.
Choose a pattern, change one thing, and look again.

Follow your curiosity

One rule. Many possibilities.

Explore a mathematical construction, a numerical model, or a clearly labelled interpretation.

Still illustration of Vesica PiscisVesica PiscisSacred geometry
Read the study

Two circles overlap. Their separation changes the shape of the shared region between them.

Try this: Bring the circles closer, then move them apart.

Still illustration of Star PolygonStar PolygonSacred geometry
Read the study

A fixed step connects points around a circle. Changing that step reveals different stars and, sometimes, separate loops.

Try this: Change the number of points before changing the connection step.

Still illustration of DharmachakraDharmachakraSacred geometry
Read the study

A radial study inspired by the wheel of Dharma. Spokes, rim and centre provide three ways to organise the drawing.

Try this: Change the spokes and look at the spaces between them.

Still illustration of TaijituTaijituSacred geometry
Read the study

A circular study inspired by the taijitu, with complementary regions and smaller forms nested within them. Its depth is an artistic variation.

Try this: Add a little 3D depth, then return it to zero and compare the flat drawing.

Still illustration of Sri Yantra-inspired trianglesSri Yantra-inspired trianglesSacred geometry
Read the study

Nine layered triangles, four pointing one way and five the other. This is an interpretation inspired by Sri Yantra, not its exact traditional construction.

Try this: Change the depth to separate the layers and follow their edges.

Still illustration of Tree of LifeTree of LifeSacred geometry
Read the study

A geometric interpretation of the Kabbalistic Tree of Life. Nodes and paths suggest its structure without replacing an account of the tradition.

Try this: Set motion on and follow the artistic wave along a path.

Still illustration of Flower of LifeFlower of LifeSacred geometry
Read the study

Circles share their centres on a hexagonal lattice. Each generation extends the repeating arrangement outwards.

Try this: Begin with one generation, then build the pattern a ring at a time.

Still illustration of Girih-inspired star ornamentGirih-inspired star ornamentSacred geometry
Read the study

Separate star polygons are arranged in rings, drawing on geometric ornament. This is not a plane tiling or a historical reconstruction.

Try this: Change Star points and compare the spaces between the stars.

Still illustration of PhyllotaxisPhyllotaxisSacred geometry
Read the study

Points step around a centre by a constant angle. Near the golden angle, spirals emerge in more than one direction.

Try this: Nudge the divergence angle and watch the spiral families change.

Still illustration of Metatron-inspired circle networkMetatron-inspired circle networkSacred geometry
Read the study

Thirteen circles and a selected connection network form a geometric interpretation. The drawing does not claim every traditional edge or a complete 78-edge graph.

Try this: Turn the form, then return to the front to compare its symmetries.

Still illustration of Golden-triangle subdivisionGolden-triangle subdivisionMathematical
Read the study

A finite patch is subdivided using the golden ratio. This drawing does not establish Penrose matching rules or an infinite aperiodic tiling.

Try this: Increase Subdivisions and follow a smaller triangle within a larger one.

Still illustration of Lissajous space curveLissajous space curveMathematical
Read the study

Three repeating motions trace a curve through space. It can cross itself. This is distinct from Ledger’s two-dimensional 3:2 drawing.

Try this: Keep the frequencies fixed and change Relative timing. Turn the view to follow the curve.

Still illustration of Mandelbrot orbit samplesMandelbrot orbit samplesMathematical
Read the study

At zero C-offset, parameters c sample the boundaries of the main cardioid and period-two bulb. C-offset shifts those samples away from these boundaries. Iterate z → z² + c from z=0; height records the iteration and escaped points are omitted.

Try this: Change Maximum iterations and compare how far the orbit samples develop.

Still illustration of Klein bottle immersionKlein bottle immersionMathematical
Read the study

A figure-eight immersion represents a Klein bottle in three dimensions. Its self-intersection is part of this representation.

Try this: Turn the drawing and look for the figure-eight cross-section.

Still illustration of Hopf projectionHopf projectionMathematical
Read the study

Fibres of the Hopf map are projected from the unit 3-sphere. A finite window omits points near the projection pole, so some visible fibres are fragments.

Try this: Reduce Fibres to follow a strand, then turn the projection.

Still illustration of Lorenz trajectoriesLorenz trajectoriesPhysics & dynamics
Read the study

A sampled Lorenz trajectory, computed with a fixed-step fourth-order Runge–Kutta solver. Optional motion turns the completed drawing; it does not advance physical time.

Try this: Change Rho, then compare the shape. Some parameters settle towards a fixed point.

Still illustration of Toroidal curveToroidal curvePhysics & dynamics
Read the study

A closed curve winds around a ring. Coprime winding counts give a torus knot; shared factors retrace a simpler curve.

Try this: Change one winding count and follow the resulting curve.

Still illustration of Spiral GalaxySpiral GalaxyPhysics & dynamics
Read the study

A stylised spiral galaxy made from points. This is an illustration of structure, rather than an astronomical simulation.

Try this: Change the arm count and notice how the centre stays shared.

Still illustration of DNA HelixDNA HelixPhysics & dynamics
Read the study

Two winding strands give a double helix its recognisable form. The drawing simplifies molecular structure.

Try this: Change the twist and watch the relationship between the strands.

Still illustration of 4D Tesseract4D TesseractPhysics & dynamics
Read the study

A projection brings a four-dimensional cube into a three-dimensional view. Some apparent crossings belong to the projection.

Try this: Set it in motion and watch the inner and outer forms exchange places.

Still illustration of Trigonometric flowTrigonometric flowPhysics & dynamics
Read the study

Sine and cosine displacements bend a point cloud. This is procedural art, not a curl field or a fluid simulation.

Try this: Set the drawing in motion and change Displacement strength.

Still illustration of Sierpinski tetrahedral studySierpinski tetrahedral studyPhysics & dynamics
Read the study

A finite chaos game repeatedly moves points halfway towards a tetrahedron’s vertices. Motion rotates the cached result.

Try this: Change Chaos steps and compare how clearly the smaller gaps emerge.

Still illustration of Cosmic web illustrationCosmic web illustrationPhysics & dynamics
Read the study

A warped point cloud suggests cosmic structure. It contains no observed data or explicit cosmological filament model.

Try this: Change Spatial frequency and compare the concentration of points.

Still illustration of Mobius StripMobius StripPhysics & dynamics
Read the study

A strip returns to its starting place with a twist. The familiar single half-twist gives a Möbius strip one continuous side.

Try this: Turn the drawing to follow the strip around its edge.

Still illustration of Black HoleBlack HolePhysics & dynamics
Read the study

An illustrative accretion disc and jets surround a dark centre. Colour and motion express the idea rather than a measured physical model.

Try this: Look along the jet, then turn to see the disc.

Still illustration of Wave interferenceWave interferencePhysics & dynamics
Read the study

Several wave terms combine into an interference pattern. This is not a quantum field simulation.

Try this: Change Frequency and look for reinforcement between waves.

Still illustration of Quadratic map studyQuadratic map studyPhysics & dynamics
Read the study

A custom quadratic map is extended into three dimensions. Escaping paths are omitted; some settings leave no bounded result. Chaos is not guaranteed.

Try this: Change Parameter A a little and compare the retained paths.
