Write creative code in one pane and watch it run in the next, with no install, no build step and no configuration.
Opens in a new tab. We do not control this site and it may have changed since we catalogued it.
p5.js Web Editor sits in Generative Art under Make, and we have it filed as coffee break — five to fifteen minutes of proper attention. It reads as brainy, useful and clever.
Algorithms as a medium: flow fields, particle systems, tilings and fractals you can steer. Output tends to be wallpaper-grade within a minute.
Botanical infinite zoom drifting through flowers, insects and quiet ruins. Best left running on a second screen.
Sculpt a glossy blob with sliders for noise, light and iridescence, then leave it rotating and admire your handiwork.
JavaScript demos in 140 characters. The gap between how little code there is and what appears is the whole appeal.
Walks you through rebuilding classic algorithmic pieces — tiled lines, Joy Division, cubic disarray — one step at a time.
Zoom into the Mandelbrot set as far as the arithmetic allows, with palette controls and no plugin to install.
Physically modelled sea you can retune — wind speed, swell, choppiness — rendering waves that behave properly.
Gallery of Processing and p5.js sketches where every piece runs in the page and the source is right there to fork.
The gentle way into fragment shaders, with every example editable in the page and redrawing itself as you type.
