I love the efficiency with which ImageMagick  has been created. The look of the user interface is deliberately simple; the software suite needs to be as blazingly fast as possible from the shell

        Hexlish Alphabet for English, Constructed Languages and Cryptography: Automatic, Structural Compression with a Phonetic Hexadecimal Alphabet

        DOI : https://doi.org/10.5281/zenodo.13139469

        Hexlish is a legible, sixteen-letter alphabet for writing the English language and for encoding text as legible base 16 or compressed binary. Texts composed using the alphabet are automatically compressed by exactly fifty percent when converted from Hexlish characters into binary characters. Although technically lossy, this syntactic compression enables recovery of the correct English letters via syntactic reconstruction. The implementer can predict the size of the compressed binary file and the size of the text that will result from decompression. Generally it is intuitive to recognize English alphabet analogues to Hexlish words. This makes Hexlish a legible alternative to the standard hexadecimal alphabet.
