Concentric circles

[Ofnuts]

With several scripts of mine, mostly using paths

• Create the inner circle path (circle selection, thenSelect > To path)
  
• Duplicate and use the scale tool in "Transform: Path" mode to create the outer path
  
• Use my ofn-path-inbetweener script to create all the intermediate paths
  
• Use my ofn-stroke-fill-path script to render the circles (one layer per circle)
  
• If necessary, use my ofn-export-layers script to export each layer to an image
  

Scripts are here (paths) and here (layers).
