Animated SVG

Something I wanted to do was to have an animated SVG as background for my site. I googled and studied SVG and animation, and did an animation like one below but slow and subtler. Then I noticed that browsers consumed quite a lot of cpu, yours should be heating up your computer somewhat already. Of what I read, browsers repaint the entire page on SVG animations.
So, I will try to come up with another concept, where the animations are not continuous, but instead does something on a timer, scrolling, or other events. Perhaps a random pattern of circles... or some fractal line thingie. Well, I guess we will all notice when I'm done... the ones of you that check up on me often...
