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.
