PowerPoint provides you with umpteen options to change the appearance of your bullet points. You can change 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.
