Mirage, Frederic Kokott
Mirage is a three minute animated short with animation and music by Frederic Kokott.

Less a story than a short audio-visual poem, it was made with vector graphics in Illustrator and After Effects, using the “2.5D parallax effect” that has become popular in making animated art images lately.

Kokott has posted some making of videos, but the parallax effect is made clearer on The Creators Project here and here (prefaced by brief ads that can be skipped).
