One of my favourites so far, we had the subject of 2d-animation in the third semester.
the biggest exercise can be seen below. we were given a short piece of different sounds and were tasked with creating an animation using only a circle and basic transformations and scales. the goal was to visualize the given piece of sound and noises.
the following three clips are very short. we had just a small fraction of a song to work with and had to create animatons, using only basic shapes.
