How do you recreate a video game using LEGO? You could build the game’s characters, or even a 3D version of a level. But that doesn’t capture the movement videogames have. Or you could do what Jason Cichon has done, and take the term “side-scrolling platformer” quite literally by turning the classic Mario Bros into a moving diorama.
The various pieces of the level are attached to a conveyor belt out of sight, and a crank on the diorama’s side scrolls the level past the viewing screen, duplicating in 3-dimensional bricks the feeling of moving through the level.
