Life Writer is an art installation created by Christa Sommerer and Laurent Mignonneau.
The project is an interactive art installation which consists of an old fashion type writer table and chair and a paper reel attached to the type writer which acts as a projection screen. Users of the installation type in the conventional way on the type writer and the output on the paper projector is a collection of virtual insects that behave and move depending on the inputted text from the user. The letters and words inputted act as a genetic code for the insects.
The insects will eat letters to stay alive and also they reproduce. Their movement speed is also determined by the input text. The user can also interact with the outputted insects by altering the typewriters paper scroll. Below are a few pics and Clip of the Life Writer.

The second reference is entitled "Biomorphic Type" and is a project that uses human responses such including heartrate, breathing, viscosity of the eye, brain activity and muscle activity to enable a typographic that responds to these senses and manipulates the appearance of the type when a user is inputting text whilst connected to the sensory equipment.
There isn't a massive amount of web coverage for this project but some info can be found here:
