Done in collaboration with the biochemist and photog Linden Gledhill, the sculptures -- which are really more like time-lapse paintings -- are part of an ad campaign for Canon's Pixma brand meant to celebrate the beauty of ink at a time when image-capture has gone almost entirely online.
They're made by stretching a balloon over a speaker, then dropping paint in the center, before blasting it with a single sharp note. The paint splashes, and a camera set on what looks like a gravity ride spins around the speaker, snapping away at 5,400 frames a second.
The designers experimented with several combinations of color, sound frequency, and volume.
