So, I'm working on an application for managing my projects and timesheets and such, and one of the things I really wanted was a decent Calendar chooser. I looked around and didn't see one, so I spent a few hours and made what I think is a nice one...

Its a single morph class, with one support class. I've attached a screenshot. I have no idea how widgets like this are typically included - either as some kind of add-on, or included with the base image.
