Allow me to finally introduce a project that has been a source of many sleepless nights, frighteningly advanced hair loss, and multiple failures since 2016: Moving Minifig Machine Like GBC, "MMM" consists of modules. The module in this thread is a Mindstorms-powered fun fair ride where the minifigs move in, jump, and then leave. See the short introduction here: The idea was born at a LEGO event. The audience always loves GBC, but most builders prefer to build city layouts. MMM is an attempt at combining the movement from GBC with minifig-scaled buildings. Modules are based on raised base plates. This allows for the conveyors and mechanical components (such as a Mindstorms NXT as seen in this module). The front wall allows the builder to showcase the name of the module. It can also be left blank as seen in the adjacent modules, or you can tape printouts onto them with some interesting information of the modules. See building instructions for standard modules here: https://brickhub.org/i/themes.php?theme=MMM The design of this module is based on the classic game Theme Park by Bullfrog which was released in 1994. The "graphics" of the modules I have built are form the 1995 port to the Playstation. This screenshot is from the DOS version: You can see a very fancy version of the in-game model in the cut scene at 8:17 of this video:   The module uses a single L-motor for the two tracks. It uses a mechanical "diode" to make the outer track go in a single direction, while the other can change direction. I show it in detail in this update: An NXT motor is used to raise and lower the jumping pillow, while the walls move in and out. Finally, an M-motor is hidden in the "pillow" to move the tracks on it that connect with the outer track at an angle which allows for entry and exit that works fairly reliably. You can see me testing it in this video:   I have tried a variety of designs for the pillow which would allow it to be built in red. Designs include rolling cylinders and free-spinning wheels. All of these attempts failed horribly, and I decided on compromising with a gray pillow. I know it is not much, but I hope that you can see the idea behind this. The project might fail - it has done so many times - but I also think it has potential. I have more modules planned and hope that you will enjoy the presentation of them. And if you think that I'm exaggerating when I say 2016, I must begrudgingly say that it is true. Here is an unlisted video of the layout as it were in 2016. The modules have since then been redesigned:
