After work today I was putting together the components that I will need to display nibbled data on a circular surface. I have all bits drafted so I thought to just generate a preview image for the NIB file I got from Ruben.
It’s not a correct visualization of track data because of edge effects that I did not remove (track data in a NIB file comes from slightly more than one revolution scan), but it gives an idea of what the final tool will be capable of doing.

The drawing is dynamically adjusted when the window is resized, so there’s no practical limit to how big these images could be generated. Here’s what the upper right part of the disk looks like in a larger version:

I will also add an option to save them to PNG.
Stay tuned for more!
