You can participate in the Search for ExtraTerrestrial Intelligence. At Home. That's right, the SETI @ Home project is one of over two dozen distributed computing projects that you can participate in from home, office, laptop. You will be donating otherwise unused clock ticks from your computer to assist in analyzing data collected from various sources. The power of tens of thousands of PCs working on a project that might only have a few hours a week of university mainframe computing time available can make all the difference in the world when it comes to finding life elsewhere in the universe, or curing terminal diseases.
