Customization
Minifig customization is the practice of modifying Lego minifigures. This can be as simple as mixing and matching parts, or as complex as remolding plastic. Some custom minifigures are made by affixing stickers or decals to the figures. There are also businesses such as BrickArms that sell custom decals and molded minifigure accessories, many of which are inspired from popular media such as films and video games. While a relatively recent phenomenon, minifigure customization has rapidly become popular within the wider building community, although some maintain a "purist" approach, using only elements produced by Lego.
Lego executives have for some years now been using personalised minifigures in place of business cards, with email and phone details on the front and back of the torso, and hair and facial features designed to resemble each executive.
