If you'd like to keep going, visit the site One Million Digits of Pi.

If you really want to celebrate, raise your glasses at precisely 9:26. Or even better, make and eat a pie at that time. And perhaps calculate pi from said pie's circumference and diameter.  In fact, if you want to see real pie's used to calculate pi, see this cool YouTube video. 

For fun pi books, check these out at your library:
