  Visualising the three dimensional distribution of stars within a
constellation is highly challenging for both students and educators, but when
carried out in an interactive collaborative way it can create an ideal
environment to explore common misconceptions about size and scale within
astronomy. We present how the common table top activities based upon the Orion
constellation miss out on this opportunity. Transformed into a walk-through
Orion installation that includes the position of our Solar system, it allows
the students to fully immerse themselves within the model and experience
parallax. It enables participants to explore within the installation many other
aspects of astronomy relating to sky culture, stellar evolution, and stellar
timescales establishing an innovative learning and teaching environment.
