from meaning to beauty
As a child, everyone decides at some point to create there very own secret way of writing. You write down the letters A to Z and start designing 26 new symbols. Not only if this not very secret, it turns out to be very hard for a child to think of 26 different symbols.
Script is an experiment to see if adults are better at this. It is an atempt to create a new, visually intresing, way to write. That has certain benifits over normal letters. For instance the abillity to integrate vowels into constants.
