The Java version of the free visualization program 3D-XplorMath has long been part of IMAGINARY. I will demo the Pascal version (unfortunately still MacIntosh only) which now has explanations for all its objects. It is also richer in animations which deform the objects or add visualizations of the object‘s construction. All 3-dimensional objects can be shown in anaglyph stereo, red-green glasses will be provided. The program is intended for individual experimentation. Its development has mainly benefitted from demo-lectures to audiences ranging from school kids (13 years and up), students of my courses and colleagues at conference evenings.
