Better Programming Through Pictures

I am currently looking again at the RUP and UML. There are several new tools that looked interesting to me as a developer for designing pictures. These are also handy if your boss hasn't been coding for a while and finds UML easier to understand a bunch of code. I especially like the idea of applying patterns to code or seeing if code requires modification to fit a certain pattern.
