Hi Hans,
To progress in the use of Metafun, I try to do the same cover page as
your document
'Metafun ". Without looking at the code (but using the definitions of your
colors), I managed to get the mosaic.
I would write the word "MATHÉMATIQUES" as you did with the word "CONTEXTEN".
Thank you,
Fabrice
