Here's an article about some wackjob (or perhaps genius?/) who invented a new alphabet years ago based not on written text but on colors. Quite simply, each color represents a letter of the alphabet. He invented this years ago, but only now felt it was ready for the world due to the ubiquity of color monitors. Frankly, I see a whole new market for little code puzzles on kids' place mats at the local Olive Garden, but beyond that, I don't see it.
The website is an enjoyable, if not completely useless and time consuming, toy for about ten minutes, but it contains many of the inventor's complex word and sentence creations with little to no explanation of practical application. Basically, the guy must have had a little too much free time in his bedroom as a kid.
