Basically, this does for videos and picture what the iTouch did with album viewing.
Take a look
here.It takes any galleries (facebook, myspace, google images) and put them into a huge scrolling gallery left to right in 3D.
It allows you to watch Youtube videos with it as well.
I just got it, it's only 1.7MB, and I love it.
It works with IE, Firefox, and Safari, on Windows and Mac.
Try it out, you won't regret it.
