The command pattern is probably my favorite design pattern, because of all the fun things you can do with it. The idea of the command pattern is to create an abstraction between the operations an object can do, its commands, and the actual commands themselves. This makes it really easy to combine together or chain different commands without having to change the code. The program can dynamically chain and combine these actions. The best part is since each command is its own object you can easily implement and undo function for each command and make a set of undo-able actions.
