Gravity

Gravity is a creative animation and effects group based in Israel. Their animation definitely made their website more interactive and interesting. There is even an animation when the page is loading, which keeps the viewers' attention when waiting for the page. The site itself is very easy to navigate with a lot of stimulation to keep you wanting to see more of their work. Everything is neatly categorized and easy to find. All the videos are quickly viewed with one click and there is more information about the project at the bottom. It is quick to exit out of the videos to go back to the previous page as well. Overall, I think this is a very unique site.
