"This uses the Bitspeech lookup tables of consonants and vowels to generate an asemic stream of words formatted into semi-rhythmic sentences and paragraph breaks."

Based on the Bitspeech lookup algorithm, a method for translating base 16 hex values into words by mapping the underlying input value into chunks of bits which map to lookup tables of vowels and consonants, Rickerby generated steam of meaningless but rhythmic words. Try to read the generated novel out loud, it feels like it is written with an ancient Northern European language, and maybe contains some kind of hex. Perhaps, it is telling a story of how powerful magic is used by and finally destroyed the civilization, so their language and cities, with the magic, are forever lost.

The orginal code in Ruby comes in 255(or 256 if you are using a PC) characters, which is incredibly small. Below is the source code.
