Has anyone written any graphical tools such as ODE Toolkit, dfield, or

I spent some time a while back working on using JSXGraph to draw
solutions and phase planes for systems of differential equations. Here
is one example:

You can drag the starting y-values on the far left up or down. You can
change the parameters in the model at the top. And you can change which
variables are in the phase plane.
If you look at the brains behind it:

You can see that it is easy to modify for other systems of equations.
Also, for Sage, I enhanced some classes for visualizing solutions of
differential equations. See http://sage.cs.drake.edu/home/pub/87/
Thanks,
Jason
