Stereographic Maze

About

Stereographic Maze is part math visualization, part puzzle game. You are navigating a maze on the surface of a sphere, but the maze is being visualized on the screen via stereographic projection---a method for mapping the surface of a sphere onto a flat plane. Imagine a globe with a 2D plane bisecting it at the equator. If you draw a line at any downward angle from the north pole, it will pass through the surface of the sphere once, and through the equatorial plane once. Project each point on the sphere along that line onto the equatorial plane and you've got a stereographic projection. The southern hemisphere is projected upward into a circle in the center of the plane, and the northern hemisphere is projected outward to fill the entire remainder of the plane. The north pole itself is lost in the infinite distance.

In Stereographic Maze, our intrepid player (a dot) starts on the south pole (which is in the center of the screen), and must find its way through a maze to the north pole (marked by a modulating circle). The corridors of the maze are along tropics (east/west lines) and meridians (north/south lines). As you appear to move through the maze, you are actually staying in place and rotating the entire sphere. The goal of reaching the north pole is equivalent to rotating the sphere so that the original north pole moves all the way to the south pole.

To Play

Controls: arrow keys (the left and right arrow keys rotate the sphere along it's normal axis of rotation, moving you east or west. Up and down rotate the sphere along a perpendicular axis, moving your north or south)

Goal: reach the north pole, which is always "up" from the center of the screen. It is marked by a modulating circle.

Difficulty: at lower difficulty, the maze is smaller (i.e. made up of fewer meridians and tropics), and there are more corridors, making it easier to navigate. At harder difficulties, the maze is larger (i.e. made up of more meridians and tropics), and there are fewer corridors. On "hard" mode, there are no loops, so you cannot make any wrong turns.

Tip: start by getting as far north (up) as possible. Once you get north of the equator, you should be able to see the north pole in the upper part of the screen. If you can't find a path there, you may need to go back south, then travel east or west to find another path north.

It is recommended to play fullscreen.
