At last I have started to make some roads into the TW and although I have been looking at the structure of the TW it is worth it to simplify it. And to make it interactive.
I feel that I have been making it too complicated to describe. It is after all just a collection of examples. But the way that they have been presented is unique. I hope the TW works! An earlier version did.
I think it's trying to answer any questions that have been posed that is difficult. One of the points is just to play with the thing! And find out.
