I know someone who has specialized in Japanese stores and gardens, He has a street full of different kinds of shops with a garden at the end of the street. He endlessly likes to show off his new additions while he shows the whole thing, again and again and again.
Have you ever heard of Giant Ball Contraption? Its where you build something that is supposed to move a LEGO ball at a rate of 1 second down a sort of conveyor of others builds.
People come from all around to connect a bunch of them together and some of the stuff that people engineer is insane.
Here’s one setup of modules from a famous GBC builder.
This is where Lego really intersects with engineering
This guy is in Japan!! Legos are an arm and a leg there. I bet this took one hell of a lot of legos to make. On top of that, it took a lot of expensive space in which to make it.
It is not only the Legos, it is the space needed for the whole contraption. I can see he is using at least two rooms. Depending where in Japan he is, this could be very, very expensive. I could only afford about one and one-half rooms while I was there as a single, and it was in a really old, traditional type apartment with a shared bath.
big kidsadult “lego engineers” would love to make this one.
