<p>I am tired of doing typical CRUD programming type applications. I would like to work on some interesting (not too hard) programming problems.  Are there any sites out there to help me exercise my brain?</p>

Project Euler:
http://projecteuler.net/
is a nice collection of randomly interesting problems.
Somewhat related (not always programming, but generally interesting to programmers) is the IBM ponder this site:
