Above are some of the emoticons I created for the Skype chat client. They're designed in the Skype house style and have to read clearly at any size from 20x20px up to 160x160px.
The core set of around 100 emoticons was designed by the great Jon Hicks. My contribution to these was the animation, trying to bring an extra storytelling element to Jon's static designs where possible without detracting from the universality of the icon. (puke) is my favourite.
And (talking) is mouthing a phrase that I'm not sure anyone figured out yet.
