The film sandwiches ever-shifting images of the band members playing instruments with pixellated objects including pink doughnuts and table tennis bats.
In the past, Schnellebuntebilder had created abstract clips, rather than stories, but the studio decided to create more of a narrative for Sissi Rada's Sunday track.
"This time we tried to combine generative elements with dreamy 3D illustrations of the lyrics," the studio told Dezeen.
The film opens on a blurry image of a human figure, which resolves itself into someone playing a guitar, before morphing into a band member sitting at a harp.
Characters continue to merge into one another before exploding into pixels, and transforming into images of rotating objects shown in quick succession.
More footage of the band performing is intercut with pixellated images of disembodied hands playing table tennis, a game controller and a glitchy black cat.
"We developed for the different parts of the clip different looks – happy and colourful for every positive quote, dark and more heavy visuals for the chorus where Sissi is singing about Mondays," the studio told Dezeen.
"The doughnut was for us a symbol for the breakfast and also for the detectives quote, and the black cat is our interpretation of the church quote," it added.
Schnellebuntebilder used a Microsoft XBox Kinect 2 to film around 40 takes of the band playing, capturing video of individuals with their instruments.
The clips were then transferred into live programming environment VVVV, which was used as an editing tool and an engine for the video's particle system.
Sunday is taken from Sissi Rada's forthcoming album Pragma, which does not yet have a release date.
