Well, I just couldn't resist. I set up a Python script to do finger spelling. It reads a text file and applies the letters to the chosen hand. What happens between the letters is sometimes physically impossible because I just let the interpolation happen, but the result is readable and might be useful for practice. (In freestuff under utilities.) True sign language (ASL) would be impossible to automate, because ASL uses its own idea of grammar and concepts that have nothing to do with written English. More like Chinese in its overall view of the world. But it might be possible to mechanize SEE (Signing Exact English.)
