We usually don't dedicate too much to GIFF creations, and have to say I'm a total fan. Even the Jellyfish website works with old school GIFF technology. Need some animated elements at your site? Newer versions of Photoshop allow you to import video directly to your project. Remember the SAVE FOR WEB function in file section and you'll have it ready to go. Wanna loop it? Don't forget to apply the repeat FOREVER and you'll have an infinite, small sized animation This means, you can import animation from any software of choice. Make some AE comp, a C4D project, some PHOTOSHOP and upload your file into flickr, twitpic, or such. When finished, link it back to your website!
