Gravity Lego Marble Maze


The cubical farm I moved into had windows in the cubical walls. This picture is when I was leaving and had put things mostly back to way I had found them. I left the white board.


Here is Charles looking at some on the Lego I had put in one of the windows. He is in the walkway looking into my cubical.


The upper window is where I would put the marble maze. The windows were not just to one side of the doorway, there were also between cubicles. The cubical walls to your left and right were also lower by a block. I could only guess the intent was to make it easier for people to pass the paperwork on to the next station. My bookcase to the left and 4’x8’ whiteboard to the right help cut down on the distraction from my neighbors who were working on totally different projects than I was.


I swapped the solid panels to the left of my doorway and put in windows with paper backing to hide the yellow backing of the pushpin board. Without the pushpin board it was necessary to find another way to hang my name board. I used some magnets from a hard drive. I had vague plans for this upper window that I never did get to.


These are some of the Legos I gave out at Yule time as part of my Distribute Distraction Of Service attack on the A.root server


The maze is 64 dots wide, just under 28 full hight bricks high and 8 dots deep, which gives it room for 3 layers. The tags ID the openings as to where they go, which layer they use, and as building landmarks. START was the bottom right. The player would get the marble to
A1 which would come out at A. The objective was to get the marble back to C. There are about twice as many blue entrances as there are red exits.


I did the design using excel spread sheets for each of the 3 layers. The lower right sheet is the front layer. The pink one is the middle layer. The upper right one is the back layer. The middle and back layers use long ramps.


Here is what the back layer looks like. The long ramps use straight railroad track from the ‘classic’ Legos. The blue ramp would take the marble ~3 seconds to drop, whereas the vertical drop on the right was Thunnk! The side index blocks are yellow and blue on the back.


Here the front side shortly after I had installed the maze. It is facing out into the walkway. Silly me cannot find any of the pictures I took of coworkers and kids trying to solve the maze. I had posted instructions about where start was. There were 3 Neodymium magnets for the players to use to move the steel marble to each entrance.


Here is the back side. The marble is on a parking ledge so it would not fall out while I was putting the maze into the window.

The maze is home with me and still intact. I have built a case for it - using legos of course - that holds sheets of plexiglass on the front and back. The case took most of a box of 2x4 bricks.
