There are so many great books written that I would suggest buying a book and enjoying.
Among my favorite authors are:
Keith Devlin (check out his latest: The Unfinished Game about the invention of probability.)
William Dunham (check out: Journey through Genius: a survey of historically important math proofs that does not require too much background)
The book that got me to return to mathematics after college was the Mathematical Experience by Reuben Hersh and Phillip J. Davis.
There's also been some fantastic NOVA documentaries (my own favorites are "The Proof" about Andrew Wiles and the "Trillion Dollar Bet" about the mathematics of finance.)
I find Wikipedia is fantastic for reference material but not so great for study material. Better for self-study is MIT online. (Here's a link to a series of excellent video lectures on linear algebra: http://ocw.mit.edu/OcwWeb/Mathematics/18-06Spring-2005/Video...)
I have my own blog about mathematics (http://fermatslasttheorem.blogspot.com) which attempts to provide complete and clear proofs for famous results in mathematics. Some months, I get as many as 20K unique visitors so you might find it helpful.

There are also fantastic links on Hacker News on mathematics. I've found some great ones about Bayes' Theorem, for example. (http://www.google.com/search?hl=en&q=Bayes+Theorem+site%...)
