Processing Foundation

25 cities are on the map, yours could be one of them!

One month left to register your city for Processing Community Day. The deadline is June 30, 2026!

This October, communities around the world are celebrating 25 years of creative coding. Host a beginner workshop, organize a meetup, give a talk, show projects, make art together, or just hang out and code.

Every PCD is different because every community is different!

What happens when we open up our sketches to the parallel power of the GPU?

In this tutorial, explores p5.strands––a new beginner-friendly way of writing shaders in p5.js v2. He demonstrates how to shift the heavy lifting of your sketches from the CPU to the GPU, rendering thousands of objects simultaneously and smoothly.

‘sin fin’ (Endless) is a meditation on our constant transformation, inviting us to value intuition and error as fundamental parts of the creative journey. 

is a generative artist, teacher, and student who treats code as a medium for artistic creation. His practice is built on the fundamental principles of design and programming, viewing the creative process as an endless cycle of transformation and learning.

Using p5.strands, the latest feature on p5.js v2, replicates a single geometry through multiple instances and modifies parameters like position and color––demonstrating how simple rules can produce complex visual results.

How to bridge the gap between simple shapes and complex generative systems? In this tutorial, explores the core principles of building organic, expressive sketches.

She breaks down the difference between random and noise, dives into coordinate transformations, and experimented with the updated color modes in the latest version of p5.js. If you’re looking to move beyond static drawings and start designing flexible, living systems, this tutorial provides a clear roadmap for your practice.

This tutorial is part of our ongoing series in partnership with the Tezos Foundation, exploring how to create with p5.js 2.0+.

📣 p5.js 2.0 Artist Series Drop #2: Featuring Tamara Moura Costa

Tamara is a generative artist based in Buenos Aires who works primarily with computational processes, exploring visuals, code, and electronics. From live performances to physical installations, her practice is consistently guided by a sense of curiosity, play, and nature.

In this release, ‘Transiciones Latentes’, Tamara explores the delicate balance between structure and spontaneity. What began as a playful sketch of tiny flowers evolved into a sophisticated exploration of tonal relationships, rhythmic textures, and the dialogue between different directions and shapes.

In her tutorial, Tamara breaks down the core building blocks of generative systems in p5.js 2.0+. She demonstrates the fundamental differences between random vs. noise, the logic behind coordinate transformations, and how to utilize the new color spaces available in the latest version of p5.js.

Alongside the tutorial, she releases her project on Bootloader, inviting collectors to explore a playful, ever-evolving atmosphere where formal structure meets unpredictable generative outcomes.

Mexico City was built on five lakes. Today, most traces of them have disappeared.

In ‘Where Has the Lake Gone?’, artist Leonardo Aranda investigates the hidden hydrological history of the city. Using a bicycle disguised as a tamale cart, Leonardo traveled through neighborhoods scanning the ground with a custom radar sensor, searching for remnants of buried waterways.

The collected data became a 3D map built in Processing, revealing fragments of the lake system still embedded in the city’s infrastructure: curved streets, too-high staircases, and underground channels.

The project asks how we might reconnect with a landscape that urban development has largely erased.

The Network Gong Ensemble Archive by elekhlekha explores how sound can carry cultural memory across borders.

Developed through the Processing Foundation Fellowship, this project documents Southeast Asian gong traditions through oral histories encapsulated in interactive p5.js sketches. Musicians from the Phillipines, Myanmar, and Thailand contribute recordings of similar instruments across different cultural contexts, revealing the deep connections that exist across these musical lineages.

Rather than treating archives as static collections, the project invites visitors to engage with the materials as a living ensemble. It is meant to be played and shared.

What really shapes a bézier curve? In this tutorial, Licia He takes a closer look.

She unpacks the math behind how bézier curves work as parametric systems, demonstrates three distinct ways to construct them, and shares her personal approach to defining control points. If you’re working with bézier curves in p5.js, this tutorial will give you a clearer mental model of how they behave.
This tutorial is part of our ongoing series exploring how to build with p5.js 2.0+.

📣 p5.js 2.0+ Artist Series Drop #1: Featuring Licia He

Licia He is a generative artist dedicated to creating artistic expressions through technological innovations. Through her research and artworks, she explores ways to record and present information around her.

In this release, Licia explores Bézier curves in p5.js 2.0+ through her project ‘DearPlotter Font Generator’: a generative stroke font-making algorithm designed for pen plotters, CNC users, and creative coders.

In the tutorial, Licia breaks down what a Bézier curve is, how parametric curves work, and demonstrates three different ways to construct Bézier curves, including a native-p5.js 2.0+ approach. Alongside the tutorial, she releases ‘DearPlotter Font Generator’ on EditArt created as a thank-you letter to the creative coding, pen plotter, and creative fabrication communities that inspire her work.
