License: Freeware
Version: 1.06 (from 7.10.2018 OV signed)
Programming languages: BlitzMax + C

On free WordPress plan I can’t put my Fractals program here to download and I don’t have an OV certificate at the moment, so I can’t publish new versions, but I might some time in future buy an open source certificate to sign the app and make the app open source.

Custom picture of size 256 x 256

The program generates the Mandelbrot set and the Julia set.


  • Both fractals can be zoomed in with mouse
  • Shows the complex plane coordinates
  • 3 built-in palettes
  • Max custom picture size 4096 x 4096 pixels
  • Max iterations 1024
  • Custom pictures can be saved as jpeg or png
  • Palette editor
  • etc.

Notice that if you try the C values for the Julia set mentioned in the manual of the program, the coordinates must be reset to default values.

Custom picture edited with GIMP. Can be used as background.

New in version 1.06:

  • No installer: Unzip the program anywhere you want
  • Saving the custom picture made more intuitive

Video of version 1.04’s palette editing:

In the color requester the texts are localized. On my system they’re in Finnish.

There’s still plenty of room for improvement in Fractals.

If you ran into problems when installing the program, you might want to read this blog post.
