What about linking them all up and participating in the Great Internet Mersenne Prime Search, or the SETI program, or I know there are also other parallel processing applications contributing to cancer research or other important issues.?

Here are some books I've enjoyed reading and would highly recommend to interested students: The man who loved only numbers, by Paul Hoffman The Wild Numbers, by Philibert Schogt Chaos, by James Gleick - this one is a classic and is a fantastic introduction to the field of chaos, fractals, etc. The Penguin Dictionary of Curious and Interesting Numbers, by David Wells - I'm reading this at present, it's easy to pick up at random and just read, and quite fascinating. How about How to Solve it, by Polya? Enigma, by Robert Harris - you can recommend the film too. Very very very good indeed. A Beautiful Mind, by Silvia Nasar, you can find it here http://www.amazon.com/Beautiful-Mind-Mathematical-Genius-Laureate/dp/0743224574 Who got Einstein's office? by Ed Regis http://www.amazon.com/s/ref=nb_ss_b?url=search-alias%3Dstripbooks&field-keywords=einstein's+office&x=0&y=0 Simon Singh's books - I know they've already been recommended but I just wanted to add my vote, they're brilliant A history of mathematics by Boyer & Merzbach http://www.amazon.com/History-Mathematics-Carl-B-Boyer/dp/0471543977 There's a few more for you.
