Thengic   

The Thengic alphabet was created by Harry Godfrey in order
to write notes in secret. The letter shapes are based on Runic
alphabets, the English Alphabet, Ancient Greek, the IAP and
early Latin alphabets.

Notable features

• Written from left to right in horizontal lines.
• Vowels are indicated by accents when they occur before a consonant,
  otherwise they are written with separate letters.
• Words are separated by two dots, while three dots mark the
  beginning and end of sentences.
• Each sentence starts on a new line and there is an extra
  line between paragraphs and after headings.
• Thengic is designed to write English, though could be used to
  write most modern, Latin based, Western European languages.
