Comment by dazedANDconfused for Try getting the plot in the Jmol viewer without assigning it to a variable, so justgraphs.DodecahedralGraph().plot3d() Once you have the Jmol viewer right-click the graph and choose 'Style -> Stereographic -> Red+Cyan'. If you are not using the notebook (ie. running Jmol as an application), you can right click the graph again and choose 'File -> Export PNG Image'. If you are using the notebook (ie. running Jmol as an applet), you can click the "Toggle Advanced Controls" buton and then the "Get Static Image to Save (Sleep)" button.This should get you some version of the image you want.Edit: Doing this in the notebook is slightly different, updated answer.

Thanks for your help. I struggled with the instructions, though, so for those with the same problem let me mention: I was working in the Sage Cell Server and still am unable to get the instructions to work. So I switched to the notebook, chose 'Style->Stereographic->Red+Cyan' and couldn't find any "Toggle Advanced Controls" button. There is, however, a "Get Image" button (I'm using Sage 4.8) below the image. Left clicking on that opened up a static version in my Chromium browser. Right clicking on the static image let me save it as a .jpg file. If you could explain more how to get a static picture from Sage Cell Server (I like to run the latest version) and/or where to find "Toggle Advanced Controls" button, that would be helpful.
