Circles in a circle and the space leftover

Generate, download and use tangent-circle SVGs (and GIFs/MP4s for animations). Also, download and use SVGs generated from Koch-style patterns like the classic Koch snowflake, meander or Greek key patterns around a circle, and even draw your own pattern and have it wrapped around a circle.

Apollonian Gasket

Fills 4 mutually-tangent circles into a full recursive gasket via the Descartes Circle Theorem.

Pappus Chain

An open, shrinking sequence of circles filling the lune of an arbelos.

Steiner Chain

Mutually-tangent circles filling the annulus between an outer and inner circle, rotating gif or mp4 or static svg.

Key Pattern

Wrap a Greek key / meander border around a circle, render just the motif on its own, or save your own reusable motif.

Draw & Wrap

Draw a pattern on a grid -- lines, diagonals, quarter circles and separate shapes -- and wrap it around a circle.

Koch Curve

Recursively bump every edge of a circle or regular polygon outward (or inward) -- the classic Koch snowflake construction.
