Okay, that's helpful. > >(I'm imagining coming back to that email years later, and wondering what > >I sent the student -- and discovering that the links are bad, and I > >can't recreate the code.

I wrote a little function that takes a singlecell URL, decodes it, and returns the Sage code: https://gist.github.com/2034051. It's pretty much one of the lines from the single cell's web_server.py, but I kept forgetting *which* line. (And which file.) So if anyone needs a script or function they can use, there it is.
