die.txt is a bio-engineered text editor. As the user types, individual words spawn outgrowths of alternative meanings and definitions. These metonyms are sucked from Wordnet, a lexical reference system developed by Princeton University.

Using a metaphor derived from medical research into skin-cancer simulations, the letter forms are generated by ‘cellular growth’, each character having a particular cell-division encoding. The sentences of newly created metonyms grow ‘cancerously’ from cells in the original text.
