Maurer Rose
Straight chords hopping around a rose curve in fixed angle steps.
Pens
Chord progress forms color bands, with a separate rose and overlay. Starts with 3 pens and works with anywhere from 1 to 8.
Settings
Petal number n, Step d°, Fractional step, Step fine-tune°, Points, Rose curve (pen 2), Second web, Second step d°.
The preview uses the default settings on A4. Press R in the app for random variations. The SVG export is in millimetres with one Inkscape layer per pen, so it works with the AxiDraw extension, vpype and saxi.
