I had created a bunch of 'somewhat smiley' faces to use as my profile pic on gtalk. What started off as just making one happy looking face, went on to me making a proper series as the need arose. Then I started noticing the trend (not particularly a 'discovery' and you may say, so what? still, since I'm not posting about about anything else anyway). As the day wears on, the smileys
always changed and almost always in the same order as below:
Morning.
Middle of the night.
I also made a pirate smiley for a friend. Here.
