First-person visualizations of the special and general theory of relativity

Visualizations that adopt a first-person point of view allow observation and, in the case of interactive simulations, experimentation with relativistic scenes. I illustrate and explain the main aspects of the visual observations, outline their use in teaching relativity and report on teaching experiences. This paper assumes some basic knowledge about relativity on the part of the reader. It addresses instructors of physics at the undergraduate and advanced secondary school level as well as their students.
