My first masterpiece was the Thesaurus. Serious effort. Took a VERY long weekend. Take every English word out of the largest thesaurus I could find (Moby Thesaurus, standard used by Linguistics people). Then I started with the word, "Word". then I cross referenced every word to every other word that was synonyms until I ran out of words. Ended up with 5 levels of words. Within each level, the words have SOME KIND of connection to each other. But why? I have no idea. Well, I have some ideas. A lot of ideas. So, I got a result. New. Unique. What do I do with it? I sat on it for a year. One day I just said,, stick it out there and let it go. So I did. I don't expect sales. I don't expect it to make sense. But it's novel and I have yet to find a good explanation for the 5 levels I ended up with. So, I just let it sit.
