Post code (and screen shots) of the use of interact in Sage here. We'll likely restructure and reorganize this, or move it out of the wiki (?) once we have some nontrivial content and get a sense of how it is laid out. This is a collection of pages demonstrating the use of the **interact** command in Sage.
It should be easy to just scroll through and copy/paste examples into Sage notebooks.
If you have suggestions on how to improve interact, add them [[interact/Suggestions|here]]
or email the sage-support mailing list. Of course, your own examples are also welcome!

This is the code and a mockup animation of the interact command. It defines a slider, seen on top, that can be dragged. Once dragged, it changes the value of the variable "order" and the whole block of code gets evaluated. This principle can be seen in various examples presented on the pages above!
