Visualisation options include colour, size, line width, and quality (smoothness of circles). \
Output to file or screen

Recamáns sequence of numbers visualised with turtle

optional arguments:
    -h, --help
            show this help message and exit
    -o PATH, --out-file PATH
            Export to file instead, postscript (.ps)
            Default: None
    -l INTEGER, --length INTEGER
            The amount of numbers to calculate
            Default: 112
    -m INTEGER, --max-length INTEGER
            Calculate up to, and stop, after number is reached
    -s SCALE, --scale SCALE
            Scale of the visuals, 2 is double
            Default: 2
    -w INTEGER, --line_width INTEGER
            Scale of the visuals, 2 is double
            Default: 1
    -q QUALITY, --quality QUALITY
            Quality of the curves, 1 is base
            Default: 10
    -e SHAPE, --end SHAPE
            Symbol to appear at the end of the draw
            Default: None

            Default: [0.0, 0.0, 0.0]
    -r, --colour-rainbow
            Rainbow gradientNote: Overrides pen colour and works better with -length
            Default: False

No parameters

Why?

I liked the visualisation and wanted to be able to create variants of it or print it.

Improvements?

More options

State?

No known bugs. Works.
