I once almost started making something I called SymPyScript... think CoffeeScript for SymPy. You'd get the syntax of something like this: http://calculize.com/pickhardt/numerical_derivatives http://calculize.com/pickhardt/numerical_derivatives But it'd convert to SymPy for evaluation. In the end I called it Calculize and evaluated it with JS instead.
