My Processing sketches

I recently* discovered a programming language called Processing, designed mainly for graphical demos. Programs written in this language are known as "sketches", and can be exported as applications or Web pages. Here are some of the sketches I've made.

Here's the description of Processing from their home page:

Processing is a flexible software sketchbook and a language for learning how to code within the context of the visual arts. Since 2001, Processing has promoted software literacy within the visual arts and visual literacy within technology. There are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning and prototyping.

Note: All sketches open in a new window. A mouse icon ([I]) indicates a sketch that is interactive. A [GL] icon indicates a sketch that requires WebGL.

Sierpinski triangle Damping (easing) example 1 [I] Damping example 2 [I] Damping example 3 [I] Shifting clouds (Perlin noise effect) [I] warning: can be laggy in JavaScript mode! Circle waves Vectors generated using Perlin noise [I] (try holding down the mouse button!) Rotating starfield [GL] Circular curves [I] (Left/right mouse buttons change direction, middle mouse button clears screen and makes it try to follow the cursor.) Dust particles Web drawing effect [I] 3D curve drawing [I][GL] (Try all three mouse buttons.) Seven-segment counter display Random connected "nodes" (Supposed to look like some of the official Processing artwork, or whatever it's called) Limited fuel + movement range visualizer [I] (you'll see what I mean if that's unclear)
