I will build a giant maze in minecraft

I am building giant mazes. To get an idea on the size, with the Big maze package (500k blocks), you can get a 19 chunks x 19 chunks maze, with a floor, a ceiling and a 3 blocks height space to walk in.

You can configure the maze with many settings, such as the maze dimensions, the start and the end locations, the width of the paths. You can give me a theme or/and blocks used to build the maze.

If you have a more specific idea about what you want I also offer some kind of advanced settings. Instead of giving me a theme, you can send me a screenshot, a schematic or a Minecraft map. You can choose whether the maze should be perfect or not and I propose two generations techniques.
