Today's goofy experiment (which I put here instead of the creativity thread because I don't have any pix).
Print out some very fine graph paper. One half the page was set to 30 squares per inch, one half to 20 squares per inch. Lines were light gray so that they were not very visible. Add some graphite drawing pencils and some cheapo colored pencils I had lying around, and I'm making pixels, but on paper.
Results were ... not good.
At 20 squares per inch, the grid is very visible and looks utterly unnatural. At 30 squares per inch, the grid is less visible, but it is very difficult to fill in precise squares. About half the time I would slop over.
In both cases, I had to go over the squares twice, once with the graphite for value, once with the colored pencil for hue. This made the process rather slow. Also, it is almost impossible to keep a consistent value from square to square. Texture creeps in, grain creeps in from the hand motion, and so forth.
I tried a part of a face (eye and cheek line) and an iso line or two. The face parts were not horrible at 30 squares per inch, but it can't compare to an ordinary sketch of the same size. The iso lines looked really bad.
I might dink around with this a bit more, but this was pretty much a failure.
