Mapping of Colours and Shapes to the Alphabet.

Colour coding was the most obvious way to start at. To literally convert the alphabets into a system of pre-defined shapes and colours. To assign each with a visual representative. Basically, creating a new visual language which relates back to the original English letters which I am already familiar with.

Replacements of these sorts have been done before as well. The music composers have been using notes instead of alphabets. The Braille is yet another example of how visual shapes have been replaced instead of the letter.
