Happy Sans is a font style that is a bit whimsy, but is not spastic, and has a cleaner look. Spaced to be close - kerned tight with some slight overlap on some characters.
Happy Sans font integrates quickly into your system and you can access the custom glyphs through any text processing application. To install a font unzip the files you have downloaded, then put the font files (.ttf, .otf) into /Library/Fonts NOTE: Happy Sans font can be used for personal projects and NFP Organisations free of charge.
