Synesthesia in animation usually brings to mind the work of Oskar Fischinger or Michel Gagné, where the visuals work tightly with music. Dutch animator Oerd van Cuijlenborg’s short An Abstract Day cuts out the music completely.
The quick sketchy movements fill out the soundtrack and play with the scene you’re making in your head. What I really appreciate is Cuijlenborg’s use of camera work and editing. Even though it’s a totally abstract film, those elements give it a grounded feeling of being in a cinematic space.
Note: While the visuals are abstract (and quite lovely), there is a NSFW scene that comes early in the film where the audio is pretty explicit, so headphone it up.
