Maze
Perfect mazes on a grid or in concentric rings, with a separate color for the solution.
Pens
Walls form broad bands. The solution gets a separate color. Starts with 3 pens and works with anywhere from 1 to 8.
Settings
Shape, Cell size (mm), Algorithm, Direction bias, Show solution, Rounded solution.
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.
