Insight is a molecular graphics suite of programs by MSI/Biosym which incorporates a lot of different methods for working with proteins in silico and doing computational chemistry. One can perform molecular dynamics calculations using various engines including Discover and charmm, the industry standard. Additionally, one can explore other aspects of computational biology such as molecular docking, electrostatics calculations, homology modelling for building proteins of unknown structure and many others.

Insight provides a nice graphical interface to these tools. This is particularly useful to biologists who do not want to write code themselves or get hung up on the sometimes nasty command line interfaces or scripting interfaces many of these programs normally use.
