Depends on browser and mouse settings (smooth scrolling on/off). However the animation and rendering is just very slow for me on Chrome + quad, about 5-10 FPS.

Depends on browser and mouse settings (smooth scrolling on/off). However the animation and rendering is just very slow for me on Chrome + quad, about 5-10 FPS. I won't even try on Android. This could have been greatly improved by using CSS3 animations, there's even a drop-in jquery library that makes this an easy fix: http://ricostacruz.com/jquery.transit/ http://ricostacruz.com/jquery.transit/ With that said, the effect is overused and tacky. Message could have been delivered more quickly and elegantly. I felt as if visiting that link was just a waste of time, like watching an old movie I've seen and looking for changes in subtitles.
