not that I am an artist, but, a tablet that:

1) as before, used real brushes,pencils,etc.
2) could detect pressure of real brushes/pencils etc.
3) use real colorants that could be extruded from the
laydown and measured colorimetrically/specctrally from the tablet
and have the color/spectrum of the colorants encoded digitally

could you make a tablet that extruded colorants and encoded
the color/spectrum digital and included the patterns/pressures of "real"
laydown instruments?
