Browsing the internet today I found an impressive piece of Open Source. By Eric Bergman-Terrel, the Open Source C# Programmable Calculator lets you program functions for the calculator using C#. It compiles the code you write it on the fly; now I know what I will use when I need a scripting system for my applications.
