GIF is as ubiquitous as the internet memes are a part of the web today. Called gif or jif, these moving images have spawned an entire ocean of creativity on the web. Some have used gifs in art installations and all the guys who remember the 8 bit game era still love gifs very much.
Rocketboom has done a great job explaining what the gif technology has done for internet culture. They also have other great videos on their site. Find them on Twitter and Facebook. Have fun
