I once visited a personal site which used a nice jQuery animation. Using the scrollbar the plugin showed different information, almost like a letter but without following a linear sequence. Something like this: 
Of course, only one square (div) was at the screen at the time.
Do you know what plugin does that? I need to do something similar ando would be very helpful. I tried searching for about one hour but I think I don’t know how is that kind of animation called, so I didn’t find anything useful, just scrolling effects like “Go to top” or plugins animating the “go to anchor” functionality.
Do anyone of you have ever seen the plugin I’m talking about?
Try jQuery Scroll Path. The demo is here.
