One of the most common, and simple, forms of ASCII art is the emoticon (emotion + icon), often used to reveal the mood or tone of a comment, and also known as 'smilies' or 'faces'. Since Slashdot (unfortunately for trolls) does not allow the embedding of objects, such as images and sounds, in HTML-coded comments, graphics must be constructed using textual characters: ASCII art. One of the most creative ways to express ones self in Slashdot's forums is with graphical, artistic representations art.
