Branching Dendrites

This award-winning aerial image by photographer Stuart Chape shows a tidal creek in Lake Cakora, New South Wales, Australia. At first glance, it looks much like any river delta, with branching dendritic paths that split into smaller and smaller waterways. That’s deceptive, though, because very different forces shape this creek. Because tides move in and out, a tidal creek is home to flows that move both directions — toward and away from the branches. That also means that flow speeds can change rapidly as the tides shift, which in turn changes which sediments get lifted, dropped, and moved around the creek bed. (Image credit: S.

#zoomasm v3.4 #release

zoomasm assembles zoom videos from exponential map key frames, as exported by #Fraktaler #Fraktaler3 and other software for
#DeepZoom #fractals #MathArt

Changes in version 3.4 (2025-06-11) since version 3.3 (2023-07-13):

- support dual channel iteration counts (N0+N1) for very high iteration counts (above 4 giga iterations)

- update to current library versions

binaries for Windows, built from Debian Linux, source for all those platforms. new homepage at

#fraktaler #fraktaler3 v3 final is still not released after almost a year... trying to squash final #bugs in the coming weeks, so now would be a good time to check the #beta to find problems, so I can #fix them...

known bugs that have been fixed already but not yet released include:

- negate Y option has bad reference leading to glitches / fantasy fractals

- floatexp opencl coordinate glitch (looks like horizontal stripes of the image repeated vertically) with deep zooms on GPU

- newton zoom dialog has been improved

- some other small things

Vintage-Style Map of the Mandelbrot Set via Kottke [Shared]

Bill Tavis designed this lovely vintage-style map of the familiar fractal shape, the Mandelbrot set. He is selling a poster version of the map, starting at the very reasonable price of $24. I don’t usually highlight the price on this sort of thing, but an unauthorized seller on Amazon was selling poor-quality counterfeits of the map and even though it wasn’t his fault, Tavis offered to replace any of the crappy maps for free. Great map, and apparently a great human who made it.
