jquery - Examples of practical javascript object oriented design patterns

Question

What object oriented design patterns do you use in your application's javascript, and why?

Feel free to post code, even if there is no formal design pattern attached to it.

I have written plenty of javascript, but I have not applied much object orientated patterns to what I am doing, and I am sure i am missing a lot.

The following are three popular JavaScript patterns. These happen to be easily implementable because of closures:

• The Module Pattern - Example (and made popular) by Eric Miraglia
• Memoization - Example by Oliver Steele
• Currying - Example by Dustin Diaz
