I continue experimenting with my CNC robot, this time using it as an acrylic pen to draw a Lissajous curve. The result didn’t meet my expectations, but the process revealed how complex machine-driven painting really is. Controlling color, form, and expression with a machine turns out to be less predictable and more challenging than it seems. This is part of the exploration to understand what actually works. https://www.youtube.com/watch?v=My-fZlPVe4A
