Thing is, that typewriter would be a bitch to use. You'd have to dab each letter on the part you wanted, and let it go "splat." Then you'd have to dab the next letter and let it go "splat." Since we're talking oils, you'd get a 2-line tall splat (uppercase and lowercase). Not only that, but unless you physically "dabbed" the key on the paper, you'd get a splat with an uppercase and lowercase letter in white in the middle of each of them. Which might be really cool looking. It wouldn't look like the paper in the carriage, though. To get the effect this setup would give you if it were real, the easiest thing would probably be to savage an inkjet and hack it. Map the keys of a keyboard to colors and set up a script so that when you hit a key, it gives you saturation of that color for that patch, and advances one keystroke to the next. That would be a task for a hacker/engineer, though, not an artist. Could you build this in a truetype font, I wonder? Something in Photoshop? I ain't no programmer, but I can "design" how it would work.
