Visualization: Oscillations of Spring- FLASH

I want to visualize spring oscillations and hence need to create a visual of a spring- stretching and vibrations. I am working in Flash with need to demo oscilations based on user input. Typically, the springs are represented as a pencil sketch like below, and wanted to check if something more 3D and natural that can be built without much complexity(e.g would like stretch/ compression shows up on color of the spring body etc). Thanks again for and guidance/ pointers.
