The remake of the Little Drummer Boy by a Winnipeg high school student demonstrates good transitions of multiple layers. Notice the drum layers and transitions with visuals. Although some may have been accidental, they layer with the visuals to create subtle points of beauty. Look at the movie with the sound turned off and then again look away from the screen with only the sound on to discover more transitions.
The weather cooperated that day, too. We all woke up to a wonderland of snow on every tree. I went out to take photos as well. Some are posted to Twitter.
