I'm not entirely sure what you were suggesting by this, but it inspired me to realise that actually a screwed-up "ick" face isn't so hard to draw if you stylise it to nearly the same extent as an ASCII smiley (although I didn't turn it sideways). So I now have an icon I'm willing to stick with, and it's thanks to you posting this. Thanks :-)

More or less exactly that. Indeed, my X-P was intended to be an emoticon screwing up its eyes and sticking out its tongue in disgust :)
