Study mappings from R^2 to R^2. Draw into the domain with your mouse, and see the image of your drawing.
The left square is the domain, the right is the range. You can edit the formulas for the map and the size of the graphs.
There is a lot of freeware to iterate a Henon map and so forth, but I wanted one that just lets you fiddle.
