CubeDude is a LEGO technic to recreate the original character using cubes, more information is available here. This is a really nice technic and I haven’t tried yet. As my default chalenge I have tried to recreate one of most iconics characters from the StarWars movies and from the comic books. Here they are! R2D2 and DeadPool!
PS.: I’m not satisfied with DeadPool yet, so I will consider it as a WIP project.
