Motion design is really important in the design process and in order to create beautiful, unique and useful experiences for the users. With motion we can drive user's attention and therefore sometimes reduce the clutter by removing unnecessary elements. Other times, motion can add that distinctive look and playful feeling to your interface. Stan Yakusevich has really good examples of motion design, they are very experimental and of course inspiring.
