I like the idea of using your speedy smilies plugin to make wordpress load faster by using sprites to lower http requests.
However, i hope you would include screenshots of how it integrates into smilies shown in comments.
Also if it can show some smilies in a pack. And make a More option to display the rest.
Kinda like this would be nice
