Free Video, Audio, and Documents on Learning Object-Oriented Concepts and UML from GentleWare

The makers of Poseidon for UML have created a series of PDFs, Video Files, and Audio files on "Object-Orient Modeling Techniques and UML".

The Course covers:

• Overview of UML and Poseidon
• Structural Elements(Object/Classes/Instances)
• Behaviour(operations/messaging)
• Inheritance
• Association, Aggregation and Composition
• Packages
• Best Practice

I just finished watching all of the videos. I feel like I got a lot out of it. I am going to go back and print out the PDFs for some bed-time reading. I've started using Poseidon to model a new app, and so far so good. I am still using the evaluation version, but the Community and Standard editions both seem reasonably priced.
