Black and white pixel patterns created at different times and in different places: Affoltern am Albis 2003, Zurich 2009, Laax 2022. Evolving an idea over two decades. First working with colors then settling on black and white. Starting 2022 with scenic snowboard sessions in the Surselva: brain freeze in the morning, pixel mind in the evening. 50 patterns built on 33 by 33 pixel grids. The two outermost pixel lines always remain blank, resulting in an inner grid of 29 by 29 pixels, prepared for an infinite variety of designs.
