Take a look at this website promoting LED lighting to save the environment. It has a great cartoonish style that is chockfull of small and subtle animations. The humour they use to present this rather boring subject works fine for me, the whole campaign is full of silliness. For instance you can watch interviews with shrivelled falcon people from the year 3023, complaining about us not changing our light bulbs. You can also see a kangaroo play the Australian anthem by the way, I am yet to figure out the meaning of his performance.
