Try http://www.animatedemoticons.net/, and click 'animated emoticons' -

- you can get quite a few emoticon packs there without adware/spyware being installed on your computer. It even has most of the Smiley Central emoticons.

Click any other link at your own risk, some of the links lead to different sites which also have many packs, but it is likely that they will install stupid stuff on your computer.
