Has he ever looked at Wolfrom Alpha? http://www.wolframalpha.com/ It can do lots of fun with math. When I was younger I used to play with Mathematica. (Software for modeling in math) Wolfrom Alpha is the company that makes Mathematica but they have a web-site that allows you to do a lot of fun stuff for free.
