Developer turns floppy disks into secret black-and-white picture canvases — pbm2track "paints" pixel art into the disk's magnetic timing diagram

A developer has created a tool called pbm2track that transforms floppy disks into canvases for black-and-white pixel art. By manipulating the magnetic timing diagram of the disk, pixel images can be "painted" onto it. The tool mis-times flux transitions to control the appearance of each dot on the diagram, creating a unique image. While the process is more of a technical challenge than a practical use, it offers a creative way to repurpose old floppy disks. The developer recommends using an open-source floppy controller for best results.
