OpenDyslexic is a new open sourced font created to increase readability for readers with dyslexia.  The typefaces includes regular, bold, italic and bold–italic styles and each letter has a unique shape and the bottoms have been thickened to give them extra ‘gravity’.  It is being updated continually and improved based on input from dyslexic users.  There are no restrictions on using OpenDyslexic other than attribution.  The font can be downloaded at http://dyslexicfonts.com.
