There's another interesting new distributed computing project on the horizon coming soon. Like SETI@Home or Distributed.net, Einstein@Home is a project aiming to recruit masses of personal computers to process data from the LIGO (Laser Interferometer Gravitational-wave Observator) project. The purpose of LIGO is to look for gravitational waves by measuring teeny tiny changes in the length of the two arms of the observatory that might be caused by gravitational waves.
From the Einstein@Home homepage:
Einstein@Home is a project developed to search data from the Laser Interferometer Gravitational wave Observatory (LIGO) for signals coming from rapidly rotating neutron stars, known as pulsars. Scientists believe that some pulsars may not be perfectly spherical, and if so, they should emit characteristic gravitational waves, which LIGO will begin to detect in coming months.
Bruce Allen of the University of Wisconsin-Milwaukee's (UWM) LIGO Scientific Collaboration (LSC) group is leading the development of the Einstein@Home project.
Einstein@Home is one, small part of the LIGO scientific program. It is being set up as a distributed computing project, which means that it relies on computer time donated by private computer users like you to search for pulsars.
