Adam Savage is a huge fan of The Shining. In homage, he built a replica of the Overlook Hotel's hedge maze model which is so awesome that... well, watch the video. I am a huge fan of The Shining, and of Adam Savage. In homage, I made this Archicad model of the Savage replica.
I used much less time, material, and skill, but I followed a similar process to that shown in the video: Figure out the grid, figure out the scale, obsess over screenshots, find good materials, and don't let it go even as it takes longer than it should.
While Adam makes clear that his model is a replica of the (prop) model inside the hotel, not a model of the maze itself (which likely does not 'exist'), my model is roughly 50:1 scale with the replica, restoring it to 'real life' scale, based on the discussion in the video.
So this is a virtual model based on a video of a real replica of a lost real model of a likely unreal maze from a movie. (No, the maze isn't in the book IIRC.)
If you want a "model" of the maze, i.e., a miniature replica at 1:50 scale, suitable for modeling the Overlook itself, you can save the whole thing as an object and then shrink it. Use the saved view called 'Top View', select all elements, then File -> Libraries and Objects -> Save Selection As... -> Object. When placing the object, link the XYZ dimensions with the chain button and set the length to about 8 feet / 2.5m. Put it on a table.
