Abstract
Two approaches are presented that allow one to place typically abstract visualizations of compressible flows or other transparent objects with refractive index variations into a realistic and easily accessible context, without the need for a large-scale optical system. Such visualizations are of great value in an educational environment, e.g., for the demonstration of flow physics and concepts to students and/or laypersons. Time-resolved visualizations offer further possibilities to demonstrate graphically the difference between what is seen with the naked eye and what is revealed in a visualization.

Acknowledgments
This manuscript contains parts of a paper that was presented at the 15th International Symposium on Flow Visualization, held in June 2012 in Minsk, Belarus. The author is indebted to his daughter, Ms. Laura Kristina Kleine Butron, for helping him transferring abstract schlieren visualizations into the real world, and to his colleague Mr. Heath Pratt for his invaluable assistance in the ballistic experiments.
