There is only one path between any two points in this maze, which was drawn using a program running with pretty archaic technology - Microsoft QBasic no less. Because QBasic didn't have good enough resolution to fit the whole maze on the screen, it was drawn in four sections that were stitched together in Paint.net and then vectorized in Inkscape. Strangely, Vector Magic gave a result with only half the number of nodes, but twice the file size.
