Caleidoscope Eye 2 - Morphing Mandala 1080p

[schizo]

I always wanted to do an animation in 1080p, but most of my favorite formulas were rendering too long for this.
Then I found a nice Julia that renders fast so this is my first 1080p animation. This time no fast zoom flight
but a morphing mandala like fractal combined with chillout music. Feel invited for meditation ...

Turn on fullscreen + HD to see the fine details!

oh, i forgot to ask:
the outer ring is sometimes flickering (several times between two frames). i have only one stationary global light and used only ambient shadow.
any tips how to avoid this? maybe using more than one light?
