These are my experiments with the Sketch library for Common Lisp, which provides a Processing-like interface for creative programming.
- Sketch (which comes with an extra SDL2-related installation step)
- random-state
- Add a soft link to this directory to quicklisp's local-projects folder (
ln -s /path/to/sketches/ /quicklisp/local-projects/). - You'll probably also want Sketch in your local-projects folder since quicklisp may not have the latest version.
- From the REPL, load the system:
(ql:quickload 'sketches). - Switch to the
sketchespackage:(in-package sketches). - To run a particular sketch from the list below, like
stars:(run-sketch 'stars).
In case this list is incomplete, you can run (print-all-sketches) to show all the available sketches.
stars: a star field based on The Coding Train's first coding challenge.heightmap: testing out my implementation of value noise (for correlated randomness).rain: rain, wind and fog. Uses 1d value noise for the wind effect, and 3d value noise for the fog (the 3 dimensions being x, y and time).unknown: recreation of the Unknown Pleasures album cover, uses 3d value noise to make the lines wobble over time.flowfield: flow field sketch based on The Coding Train's video.dots: particles move around a flow field and displace dots.snow: mountains and snow.growth: colourful blobs growing randomly.groove2: recreation of a piece I saw at the Institute of Contemporary Art in Boston.mandelbrot: the Mandelbrot set.squarez: a grid of white quadrilaterals on a black background, inspired by a t-shirt I saw.xmas: recursive Christmas trees, in the colours of Palestine.invaders: a skeleton implementation of Space Invaders that I did for my Recurse Center application.toast: a piece of toast that bounces and always lands on the wrong side, contains a crappy/non-general implementation of Verlet physics.reaction-diffusion: visualisation of the reaction diffusion model, based on a Coding Train video.palette: for testing out colour palettes.trees.recursive: random trees drawn using recursion.trees.oo: random trees drawn using object-oriented modelling (with leaves!).trees.lsystem: random trees drawn using an L-system.swirl: particles spiraling towards the center of the canvas and leaving a trail in their wake.reuleaux: reuleaux triangle rotating in a square.
