Symbolic Calculations

For those wanting to do analytical quaternion work within Mathematica, you may want to start with this notebook. Quaternions are treated as a 4x4 real matrix which can be treated symbolically. Given the high cost of such commercial software, I am shifting over to Sage, an open source alternative written in Python. On many animation pages, you can see links to the notebooks.
