This has been one of my favourite videos to watch, it seems to have characters but the video mainly consists of just shapes and their movements making them look characteristic. I like how clean cut it is with out any rough lines as would been seen if everything was drawn. I will have to search more in depth on videos like this to see if this is an idea I would like to take further.
This animation is similar to the video above but not as professionally done I feel. It still follows the guideline of using shapes to make their frames. I like the idea of just using black and white in my final animation with maybe a splash of one other colour at certain moments to emphasise something.
