Dear all,

I am quite new to context (but love it) and i am trying tind a way to typeset texts "properly kerned" in such a way that the characters be all rotated with tiny randomized angle (strange project indeed). I tried to do it by writing a macro inspired by \followtokens. I have two questions :

1. It works but just for text within a single line : I have no clue how to manage the line breaking, and I have to admit that I don't know eanough TeX ConTeXt to find out.

2. In playing with the macro followtoken I happened to write two files with no apparent significant difference (I mean for me) but which give quite different results : one properly kerned, and another that is not. Could someone explain me what's happening here ? (files attached)
