A recursively generated tree is simply _a branch with a tree on the end of it_.

Cellular automata - randomly picks one of: Conways Life, Semi-vote, Vichniac vote (stable & unstable) or Fredkin. Renders using _big-bang_ onto a canvas element, but could probably be written more efficiently using _core.async_ more intelligently.

The Barnsley Fern is a fractal named after the British mathematician Michael Barnsley who first described it in his book _Fractals Everywhere_. The fern is one of the basic examples of self-similar sets, i.e. it is a mathematically generated pattern that can be reproducible at any magnification or reduction. Like the Sierpinski triangle, the Bar…

Around 1960 the American mathematician Sherman K. Stein discovered a curious pattern in the Sanskrit nonsense word _yamátárájabhánasalagám_. The composer George Perle told Stein that the stressed (_á_) and unstressed (_a_) syllables form a mnemonic for rhythms, and correspond to long and short beats. Thus the first three syllables, _ya má tá_, h…

Explore a variety of polyhedric solids: ClojureScript demo using big-bang for orchestration between GUI components, and the wireframes library for 3D rendering. The polygon data files are derived from http://www.netlib.org/polyhedra/, and read using abstractions over XmlHttpRequests and core.async. NOTE: Some of the shape files do not have prope…
