PowerPoint provides you with umpteen options to change the appearance of your bullet points — you can change the bullet styles, format the bullet size and its color, and use pictures as bullets. In addition, you can use a character from any font, including dingbats as a bullet. So what are dingbats? Dingbats are fonts which contain decorative symbols rather than alphabets and numbers. Wingdings is a good example of a dingbats font since it is installed by default on all computers.
