Stella2Java
Stella2Java is a tool that creates interactive java applets from the Stella models. The process is form-based, requiring a cut-and-paste copy of the equation files from an existing Stella module, followed by an opportunity to customize graph and slider bar settings. www.shodor.org/stella2java

Tools
Function Flyer is a tool that allows for exploration of how constant values affect the behavior of functions. Data Flyer is an extension that allows for plotting and fitting of data, and with the customization tool particular functions can be hard-wired into a custom data-fitting flyer. www.shodor.org/interactivate/

This series of applets behave like graphing calculators. Simple Plot plots ordered pairs as a scatter or connected graph, Graph Sketcher plots graphs of functions, Graphit does both. www.shodor.org/interactivate/
