Peter Coad’s Color Modeling method is a simple, effective technique for building robust, elegant object models. One of the best ways to learn the Color Modeling approach is through an interactive demonstration. In this session, Daniel Vacanti and David Anderson will solicit examples from the audience and—with no preparation and using the Color Modeling approach—build a real, working model for each selected problem domain in the short time given. Both David and Daniel have used this demonstration technique with great success at previous conferences, tutorials, and commercial engagements.
