This page had way too much going on. I'm interested in the topic, but couldn't get past the introduction with the constantly moving background.

Seconded. I stopped reading after a few paras because the revolving background gave me a headache.

Right there with you. Even just making the content background solid would help a little...

Although I really am not sure why you'd want a moving background at all if you have actual content that you want people to be looking at.

You can click "stop animation" at the bottom right to turn that off.

I didn't notice such an option - so the UI doesn't lead to that.

But it was really hard to read due to the movement.

noscript is great for stuff like this.
