Hi Hans,

I tried your code (so beautiful and simple!): it properly stacks the frames 
but places the text for each level, not midway between frames as desired, but 
in the middle frame (on top of one another).

Anyway, the following file illustrates the exact effect I'm trying to acheive 
(note the final overlay of some text across all four levels). I certainly 
would prefer to do this the ConTeXt way (e.g. is there a better way to stretch 
the word `testing'?)!

Thanks as always for your guidance and help.

Best
Idris
