As you could see in the video, this is the latest shop in the Theme Park layout. It is a LEGO Boost Hub-powered version of the Balloon World shop from the video game. The illusion consist of swapping minifigures in order to make it appear as if they purchase balloons inside of the shop.   The building itself is filled with strange angles and I have tried to go overboard with building techniques to make this happen: There are two different ways of making the angled walls, and the upper roof uses strings with bars to create the sunken effect.     On the backside there is a much more structured construction, which makes it easier to lift and repair the model: The woodwork and strange angles all over the facade is not exactly robust. Here it can also be seen how the Boost hub has been included to power the module.   In this picture you can see how hinges are used to angle the walls.
