Playstation into Supercomputer

From StrategyPage:

The Cell Processor on the PlayStation 3 (PS 3) is also a GPU, and that GPU alone was used to built several of the fastest supercomputers on the planet. But military researchers were quick to note that some versions of the PS 3 could be tweaked to run Linux, and the software required to produce supercomputer results from the PS 3s Cell processor. Since the PS 3 is sold below cost (so buyers will purchase lots of very profitable games), the U.S. military has bought thousands of PS 3s and used them as inexpensive supercomputers.
