I'd say stick to classic smileys rather than go down any other route. If you could do a smiley version of :mother of god: (spaced for obvious reasons) - not sure how but the right hat and shades on the jawdrop one might work. And a :whathasbeenseen: one? smiley, but elongated with hands to the side of the face a bit like a smiley version of Munch's "The Scream" maybe?
If these ideas are crap then it's because I'm caffeine deprived.
Hmm I also like the idea of sticking to the original smiles. Im a tad confused about whathasbeenseen...but I was somewhat able whip up a MOG smiley....without the hat...
Or
If someone can find me a proper hat I will try to put it on Founds some hats
or
And viper please o please add a smiley button to the Quick reply box
Im pretty found of the 1st and the 4th because of the bulging eyes but my OCD says they don't look like the ones we have now but I would be happy to clean up and resize any smiley which you guys agree on.
