Presentations with Mathematica

Mathematica’s unified computation and dynamic document architecture makes possible a new level of interactive presentation—notably allowing finished “slides” on which full interactive input and dynamic computation can still be done. Mathematica’s cell-structured documents also conveniently allow calculations leading up to graphics or other elements to be maintained in the underlying document, but hidden for presentation.
