Boston-based motion graphics designer Matthew DiVito (aka mr. div) is probably one of the most popular artists making animated gifs today. DiVito works with a combination of After Effects and Cinema 4D to create each image which appear to be inspired by 1970-80s era motion graphics with a distinctly modern twist. These are just a few of my favorites, but you can see dozens more right here: http://mrdiv.tumblr.com/
