As anybody who uses firefox knows, there are some awesome applications out there for it. Recently I came across this really cool one called PicLens.
When doing something involving lots of pictures i.e. a google image search you can click on any of the pictures and 'blink', your screen is black. Then there are thumbnails stretching off into infinity.
All in all it is a fun, cool and slick way of browsing through lots of online pictures at once.
I believe it also works with IE and Safari but who cares. Firefox is way better.
