As he couldn't understand the lyrics, he simply listened to the music and tried to guage a feeling that he wanted to convey.
"Because Laya Snin gives such a sweet and beautiful feeling, I wanted to work with flowers – roses to be exact," Rongen told Dezeen. "I think the shape of the roses is beautiful and gives a sweet vibe."
"I still don't know what the lyrics mean, so it's all about the feeling".
To create the visuals, Rongen used a fishbowl filled with water and flowers. He then dropped paint and other liquid materials into the water, some of which he had heated up to make them react differently once submerged.
This technique can be seen in the video he created for his own Shortcutz film under the moniker Hyde Park, and the visuals used to accompany Julien Mier's Sea of Decay track, which was inspired by the colours used in a film by Japanese animation house Studio Ghibli.
"I always use the same method," Rongen said. "I fill my fishbowl with water, play the music in the background and try to capture the music in colours and shapes, using different materials and paint."
"For this video I worked with a different light setup and also mixed new materials together," he continued. "A new technique I also discovered was using the microwave – it make some liquids more fluid and affect it in a different way."
