Did you know that you can make a super computer by networking Playstations together? I guess the 7 core “cell” processor is really great for super computing and computations that can make use of parallel computing. Also its much cheaper, $300.00 per “cell” as opposed to $5,000.00. All you need is a dvd copy of linux, a flashdrive with the cluster SDK on it and well…. a very large math problem to solve.
