1. A simulation system comprising: a processor configured to generate a virtual representation of a physical interaction with a material based on modeled deformation characteristics of the material and data representative of the physical interaction; and a touchscreen adapted to (i) display the virtual representation of the material; (ii) receive as input from a user the data representative of the physical interaction, wherein the user inputs the data representative of the physical interaction by interacting with the displayed virtual representation of the material, and (iii) display, in real-time, the virtual representation of the physical interaction with the material.
