For Lionel Groulx station, I have painted small wooden disks and have aligned them to recreate the hypnotic floor tile pattern. With the use of a robotic rail and long exposures, the coloured disks are "pulled" across the image plane creating the transparent, layered, 3D effect.
I'm excited about the process. It's an interesting mix of screen printing techniques, painting and photography. There are some really interesting possibilities and it's fun to experiment.
