Developer Rebuilds 1991 DOS Maze Algorithm in the Browser After 35 Years

A software developer has revived a maze-generation program originally written in Turbo Pascal on a DOS machine in 1991, porting it to the browser using TypeScript. The algorithm was not intentionally designed as a maze generator — it emerged from experiments with recursive tree-drawing routines, where branches arranged at 45-degree angles naturally produced cycle-free paths. The developer notes that the approach is functionally equivalent to randomized depth-first search, a technique that gained wider recognition through Jamis Buck's 2011 blog series on maze algorithms, roughly two decades after the original code was written. No invention claim is made; rather, the author describes independently arriving at the same method through visual and geometric thinking rather than formal algorithm study. Notable design choices from the original code — including a precomputed permutation table and using pixel color as the sole occupancy map — have been preserved in the modern rewrite.
