This is a very simple animation the storyline is almost none existent and it’s not made to be a funny or interesting video. The further in you get to the animation the more complicated the design becomes which adds more depth to the video even though it is simple. As complicated as the design and effort in to it goes its not all that interesting and doesn’t hold your attention very well.
Similar to the flash animation shown before you can see that from the use of shadows more depth has been added to them. This is another very simple animation but due to the fact that it is kept extremely short it doesn’t lose your attention.
Animator vs animation has the opposite effect to the first two examples that I have given, it has been made with the sole intention of keeping your interest and instead decided to use really simple drawings rather that fussing over adding too much detail.
