== Fractal passion ==

The discovery of the [[http://www.skytopia.com/project/fractal/mandelbulb.html | Mandelbulb]] awekened my old
passion for fractals.

So I took the time to re-encode my old rendering of the [[http://en.wikipedia.org/wiki/Quaternion | Quaternion]]
[[http://en.wikipedia.org/wiki/Julia_set | Julia set]] done with POV-Ray. Behold:

{{pictures/julia4D/julia4D-640x360.ogv | Quaternion Julia 4D fractal (640x360 @ 1200Kbit/s, Ogg Theora encoded)}}

The sound track is [[http://lite.modarchive.org/index.php?request=view_by_moduleid&query=59288 | UranChrome]],
an old-skool Amiga SoundTracker module composed by TorbJ0rn in 1989.

If your browser sucks at HTML5, you can directly download the video files, available in several formats:
