On this site I really like the use of JQuery scrolling, especially on the "collections" page. There are a bunch of different elements that scroll into place at different times which makes for a nice effect. I also like that when you move the mouse around over an image, the photo shifts ever so slightly which gives the page dimension even though its very subtle.

On this site I really enjoy the animation, which is of drawings being done in front of you. I also really like the navigation that appears once you've made it to the bottom the page. I find this quite convenient because you don't need to scroll back up to the top of the page to then switch to another page.

On this site I really like that when you scroll a bunch of scattered images move towards each other until they've formed well known faces. It is a creative concept that goes quite well with the site's catch phrase, "millions of images. endless possibilities."
