Folding@home is a distributed computing project -- people from throughout the world download and run software to band together to make one of the largest supercomputers in the world. Every computer takes the project closer to our goals.
Foldit is an experimental video game about protein folding, developed as a collaboration between the University of Washington's departments of Computer Science and Engineering and Biochemistry (many of the same people who created Rosetta@home).



GridRepublic is a customized version of the BOINC software designed to simplify installation and participation by the average computer user.
