Yuck. It's like designers are going crazy with animations just like when they learned about drop shadows, it's too much. Keep it simple and minimal. I checked their homepage and the animation of the silver box brings too much attention to it as well. You want the user to click on the green join now button but instead you bring attention to a graphic? The UX doesn't make any sense.
Animate what's important....not things just because you can.
That's actually a good point, and we're currently working at getting rid of this animation for this exact same reason. Sorry if you had a bad experience because of that.
We like using CSS animations as long as they don't hide any content, because we think they create a much more enjoyable experience on our marketing pages. We try to use them only when it makes sense, and in that case, indeed, it does not. Thanks for the feedback.
I found the animations to be subtle and are clearly contained within their area to the point where they don't distract from the content, especially on their "About" page.
Things weren't flying across the screen over text -- they simply have a small embellishment keeping me interested a little bit more on the page instead of clicking over to a different site.
I was so ready to be the critical complaining guy in this thread... animated web pages are one of my top "don't do things just because you can" pet peeves. But the animation here is actually fine, it isn't hindering my access to content, it isn't jumping around and forcing me to look at it, etc.
Nicely done.
To others that would like to add some dynamic animation to their pages: take notes! keep it subtle.
