Actually on a little more thought, it is just the point that Scott already
made. VPython provides an environment of instantaneous visual feedback.
Visual business can be conducted from the command line. Change the color
attribute of the object, and the color of the circle instantaneously changes
- not even "no compile cycle", no rerun of code of any kind. The object
seems in fact like an object - conveys some sense of tangibility, as an
And thereby seems to exist in an environment naturally adaptable to the
teaching task at hand.
