I remember in the 90s, there existed a Unix command line utility named
smiley that decoded emoticons. A sample use would be like this (the output is likely not the exact output the program gave):
$ smiley ':-o' :-o surprise
I've tried to search for it, but couldn't find it. Does it still exist, and if so, where can you get it? I'd also be interested in any other information you may have about it.
