On web sites, instant messengers and online games, text emoticons are often automatically replaced with small corresponding images like the ones on the colorful balls featured in today's new puzzle. In 1963 the "smiley face", a yellow button with two black dots representing eyes and an upturned thick curve representing a mouth was created by freelance artist Harvey Ball. This smiley presumably inspired many later emoticons; the most basic graphic emoticon that depicts this is in fact a small yellow smiley face. Digital forms of emoticons on the Internet were included in a proposal by Scott Fahlman of Carnegie Mellon University in Pittsburgh, Pennsylvania, in a message on 19 September 1982. Nowadays emoticons are available in most web or mobile applications that offer text input to the user; they sometimes come bundles in some fonts, have a diversity of colors, shapes and themes and sometimes are also animated or surrounded by animated effects.
