The Kaleidoscope referred to is a JPT version of Michael Wick's
Kaleidoscope submission.


Comments on Rasala-Proulx-Raab (by Richard Rasala):

The purpose of the Kaleidoscope was to create a case study in
object-oriented design that resulted in a beautiful program to
watch and a worthwhile program to study in depth.  The design
of the program should support a mixture of shapes and images
in the kaleidoscope windows.  The shapes could furthermore be
standard Java shapes, polygons, or smooth Bezier cubics.  The
shapes and images could be subject to affine transformations
or mutations that could operate either on the collection of
objects as a whole or on each object separately.  In addition,
using mirror reflections, a particular angular region of the
kaleidoscope region would be reflected around as in a real
keledioscope.  The angular region should turn smoothly using
real-time animation.

The author believes that the complexity of the interactions in
the Kaleidoscope program makes it an excellent case study.
Indeed, the author has continued to study and modify the code
since the OOPSLA 2002 workshop on Killer Examples.  At some
time in the future, a revised Kaleidoscope with the additional
bells and whistles will be posted at the JPT web site:
