Mazegenerator like 3D Monster Maze

[dr beep]

Anyone with ideas how to implement this maze generator?
Someone has a source.

Trying to built this generator in less bytes possible for the 1K hires version in 2D.
Ideas are welcome (with tribute mention for the one who helps me out).

I have an idea and first results are nice.
Generator app. 100 bytes without mazedata. Total will be app. 200 bytes.

I am getting nice mazes. The mist of time only needs a second to generate the maze.
