Create a fractal castle made of miniature copies of itself

Castles is a fascinating web toy by Nico Disseldorp. Left-click to add a castle to the outside of your castle—and watch as every part of the castle, including the added part, changes to reflect the form of the new whole. Right click to spin it around so you don't go mad. He's made other mind-melting recursion toys too. Read the rest

Animated fractals in your browser

Click to zoom into Jonathan Potter's spookily beautiful-animated Julia set. The trick: webGL shaders applied to the scene, making it pulse and glow and coil like a dreaming machine. He also made a Mandelbrot in the same style, without the shaders (which limit how far you can zoom.) [via] Read the rest

Video feedback emulator generates gorgeous glitchy art

Thea video feedback emulator offers a vague memory of fooling with video cameras and a strong flavor of crisp and fractal generative art, The results lurk somewhere between the decades. Click and drag your results for wild (and often brightly-flickering) variations. The creator explains how it works. [via Github]

What we’ve found most interesting about video feedback is: the sheer complexity of the images it produces through such simply-defined and implemented spacemaps that really only have to do with the relative positioning of two rectangles. It’s somewhat intuitive, but always surprising.

This is all just scratching the surface of the mathematics behind the patterns that video feedback is capable of, but hopefully it’s good enough for a start!

P.S. You’ll notice that many of the “interesting” patterns contain regions of diverse sizes. That is, they appear to have a broad range of spatial frequencies. What’s up with that?

Echo Observatory: beautiful, tactile fractal explorer with knobs on

Love Hulten writes, "The Echo Observatory is a handcrafted tribute to fractals and self-similar patterns. It's a mysterious artifact that both generates and visualizes complex mathematical formations, in real-time." Read the rest

Real-time fractal zoomer on the web

Following up on yesterday's fractal fun, here's a real-time fractal zoomer on the web.

Use the arrow keys to pan, A and Z keys to zoom, S and X keys to change the threshold.

It's by Jonathan Alpers, using WebGL and Three.js, and was featured on Chrome Experiments in November. Read the rest

Fractal fun on the web

You like zoning out in front of fractals, right? Of course you do!

FractalJS is the easiest fractal zoomer yet: just pinch-zoom or scrollwheel and watch it go. There are several sets to choose from, a smoothing option, lots of color schemes, and it's all open-source.

Alternatives: Calvin Metcalf's Leaflet has Google Maps-style controls and Alson Kemp's WebFract3D renders sets in three dimensions for an especially bizarre experience.

Bonus: Here's a Mandelbrot set being generated on a 50-year-old IBM mainframe.

Beautiful fractal landscape seems like eerie, epic ruins

"Poetic Fractals," writes Julius Horsthuis. "I use fractals for developing skills – they are exercises in framing, composition, typography, color and style."

In this four-minute journey through a computer-generated world, we see landscapes and massive fractal structures that seem eerily reminiscent of abandoned human places.

Understanding the Sierpinsky triangle

I still don't understand it, obviously, but "the sierpinski triangle page to end most sierpinski triangle pages" has some sweet fractals on it! The one above clearly depicts the optimal pattern of berms and defenses to be constructed around the Waste Isolation Pilot Project in New Mexico, lest future generations wander too close to its irradiant embrace.

Giant Origami Fractal

A three-dimensional, modular origami fractal has taken form for the first time in the history of the world—and perhaps the universe—at the USC Libraries in Los Angeles.

Acrylic fractal art made by bombarding slabs of plastic in a particle accelerator

Todd Johnson's Shockfossils are "multimillion volt Lichtenberg figures in acrylic." He masks acrylic slabs with lead and then rents time on a commercial particle accelerator and the result are beautiful, fern-like fractals.
