I use a black an Red theme with my Linux OS.
This is the perfect one that Firefox offers. I am a UI Designer. Soon I will be making my own Themes for everyone to use. The animation on this theme defiantly Rocks! Great Job!!!

1st of all, the animation speed is perfect. Nice and slow.
Themes from other developers are way to distracting.
2nd, The colors chosen are perfect.
Sure there are a billion red themes out there. but this particular hue, shaded the way it is and your choices about were to have translucent effects...its perfect
3rd but not least is the design. Its wonderful.
Even though it moves slow and is not a distraction in the corner of my eye, when I stop to look at directly, Its full of life and movement with all the pins of light.
Red is my favorite color so that's why my review is here.
But I have all the colors and the spiral theme as well.
Thank you Pavol.
