The Alphabet Synthesis Machine
"The Alphabet Synthesis Machine is an interactive online artwork which allows one to create and evolve the possible writing systems of one's own imaginary civilizations. The abstract alphabets produced by the Machine can be downloaded as PC-format TrueType fonts, and are entered into a comprehensive archive of user creations. The products of the Machine probe the liminal territories between familiarity and chaos, language and gesture."
