Resumen
| Descripción | A triple-spiral labyrinth (variant form without any wide "wall" area near the center). For another version of this, see Image:Triple-Spiral-labyrinth.svg . Note that the short path inwards does not lead to the true goal in the center. For a basic triple-spiral symbol, and cross-references to further variants, see Image:Triple-Spiral-Symbol.svg . |

%%%%%%%%%%%%%%%%
% PostScript program to display an Archimedean spiral by approximating
% it with Bezier curves. Can display a double spiral (two spirals
% rotated by 180 degrees with respect to each other).
%%% Parameters:
% centerx = horizontal coordinate of center of spiral
% centery = vertical coordinate of center of spiral
% rotf = degrees to rotate
/sepwid 110 def % width separating successive turnings of spiral
% (half this if double spiral is selected)
% incrm = insert a curve point every these degrees
/sweeps swp2 def % number of 360 degree turnings to show
% double - 0 to display single spiral, else double
