A magician is a person who can make you disbelieve your own eyes by doing something you believed to be impossible. The magic woodcarver does that by carving things that seem (almost) impossible. Traditionally wooden chains and balls in cages have been favored projects, also for me at the start of my carrier. Over the years, however, I have managed to expand the range of projects by introducing entirely new and vastly more complicated types of models to carve. I have used creative geometric tools to achieve this goal. This paper explains two of my most successful geometric methods.
