A picture posted by lonelyto25 made me realize that I had never visited the maze in fly mode (which is how lonelyto25 got his maze picture).  I entered the maze in the normal way -- inside the Maze Runner -- but then exited the runner by using fly mode.  I then toured the entire maze, which IMHO is one of the most amazing structures in realMyst.  Below are images from that tour along with some commentary. 

Well, Selenitic's been fun but it's time to get back to Myst Island.  Ooops -- the Maze Runner is missing!  Guess I'll have to get to the maze on my own.
It's down the shaft we go!  And down, and down, and down.  Wait -- let's bop outside for a minute and take a look at where we are.  Okay, now back to our freefall.  Well, I sure hope there's something down there, otherwise I'm in a heap of trouble.
Thank goodness, there's the Maze Runner.  Let's get down there and get it going.  Ooops!  Overshot my mark.  Aah, there we go.  Looks in good shape.  Hmm, no one at home.  Guess I'll walk.
Wandering around the maze, you may be tempted to hop down or up a level -- don't, they're dead ends and it's a long way down.  And speaking of dead ends, there are plenty of them.  Catching sight of the next station is comforting but always presents a new problem:  Which way to go?
The geology of the maze is interesting and varied.  It's also very thin.
At last, the final tunnel.  Okay, I admit, I took a shortcut.
And now, time to head home.  Ooops!  I'm still on zero gravity!
