At first, the exceedingly high cost of the computer hardware and software required, restricted the use of these tools to a relatively small number of well-funded researcg groups. Over the past few years the cost of high-powered computing hardware has dropped dramatically. At the same time, free, or relatively low cost, molecular modeling software has become available. Computer-based molecular modeling is now in the hands of the common man.

Humans are very visually oriented.
Much of what we learn and understand about the world around us we first absorbed through visual images. Providing students with the tools for visualizing and interacting with three-dimensional models of molecules can only help to spark their imaginations and interests in learning more about the substance of Nature.
