       - self = receiver
       - _cmd = selector
     - You can use methodForSelector: to bypass dynamic binding... but, it's kind of cheating since this method is provided by Cocoa.
+    
+- Dynamic Method Resolution
+  - @dynamic propertyName;
+    - Core Data NSManagedObject does this.
+  - You can implement resolvedInstanceMethod: and resolveClassMethod:
 
+- Dynamic Loading
+  - System Preferences modules
+  - NSBundle
+  
+- Message Forwarding
+  - forwardInvocation: (it's kind of like Ruby's method_missing)
+    - (void)forwardInvocation:(NSInvocation *)anInvocation
+    {
+        if ([someOtherObject respondsToSelector:

+  - Forwarding mimics multiple inheritance
+    - provides features of multiple inheritance
+    - but, multiple inheritance combines capabilities in single object
+    - forwarding provides abilities in smaller objects, associated in transparent way to the message sender
