[NTG-context] Emoticons ;-)

Dear all, I hope this doesn't get me banned from the ConTeXt list. What is the easiest/best way to add emoticons in ConTeXt as letters/symbols? In LaTeX, there is a package wasysym that gives \smiley and \frownie. It appears to be based at least partially on MetaFont code by Taco from 1998? I am aware that one can use images as characters as well, but I am looking for a cleaner solution. Incidentally (and irrelevant for my current purposes), my dream/nightmare would be to have animated emoticons in a PDF file. Is that at all possible? Thanks, Matthias
