The Dot and the Line- A Romance in Lower Mathmatics.

The Dot and the Line is a short animation that tells the story of a line that falls in love with a dot. I like the way the sounds chosen represent each of the shapes, for example the squiggle has a wild and unruly and fun sound, whereas the the line has a smooth sound and the dot has a upbeat bouncy sound. 
This animation is mostly about the story, however moments like with the doorbell, the sound is represented in harsh red lines. And sounds and feelings are embodied in the shape of the line. 

In this animation, I think the parts with the squiggle are the best representations of sound as image.
