1. The piece that is love is Passe-Temps (Hobby) by Mat Durand.
•In the video, there are some shapes that in the end build a face.
•There are basic shapes with some animated drawing inside. The movement of the shapes is affected by the music.
The audio is made only by sound effects.
• The moment where the animation became special is when the cube starts to transform into different shapes according to the music.
• I think that all the elements fit perfectly together. The story, the music, and the animation create a perfect piece.
2. The left video is superior because it has motion blur and it has more precise speed that follows gravity.
