Chat Avatars

Hi, We need a set of 32 custom, small avatars suitable for an online chat. They have to be small and suggestive on 20x20 pixels. A very good example of what we want can be seen here [login to view URL] (you can notice that they are very small yet suggestive, this is very important). Just like the example link above, these avatars should be somehow different as subject (we don't need only "cartoon faces" or "flowers" or "stars") but the design style should be the same. The final avatars should be at least 32x32 pixels and use progressive alpha channel (png and transparency). Preferable but not mandatory is that the final set should be delivered as a layered PSD or TIFF file (color layers have to be separated so we can change them, no other modifications will be done). P.S. We need to see some similar work (icons, avatars) before we start.
