In the Fall of 2006, Michel Gagné was contacted by Brad Bird to create a series of animated vignettes for his movie Ratatouille. The concept was to design and animate abstract representations of what the character was tasting. After discussing ideas and concepts with Brad Bird, he created a series of images to illustrate potential ideas of how the taste could be visualized in an abstract way. These were reviewed by Brad and shown to the music composer as inspiration.
A great example of how to make something abstract like taste very concrete.
