Nikola Irmer wrote in her Introduction about Kern’s work:
Kern’s paintings are an accumulated history of their own making. The paintings are worked up in many layers, beginning with the initial scenario under investigation, setting the scene. With each progressive layer the cubes’ evolution, their growth, colour, position and movement in space as well as their realtionship towards each other is traced, the positions at which they arrive are tested and pushed towards a point at which the image can rest. This stage is documented before the painting process continues. Pentimenti and animated films show the different stages of one painting’s transformation and are a way for the viewer to share in the painting’s evolution.
