Over the years, various ideas for the mechanical generation of palindromic sentences have been published in Word Ways. Of these, the simplest in concept may have been Dave Morice's Palindromic Slide Rule (August, 1995). This device separates palindromic passages into paired segments comprised of single reversal words; by shifting the positions of columns of such words with respect to one another in slide rule fashion, users can generate up to 10,000 different palindromic passages.
