I've managed to write a programme to generate the locations of the atoms in the structures that I'm interested in.
They are suitable for any molecular modelling program, I have used Jmol: an open-source Java viewer for chemical structures in 3Dto view them. Jmol can be downloaded from the above link and will run on most platforms. Download the jmol files and you can run them on your own computer.
Or more simply, you can jusr click through to the web page for each structure and jmol will run in your browser (hopefully) It certainly works in Safari on a Mac, I haven't tested it in other browsers yet.
C60
This is the fundamental molecule, composed of 60 Carbon atoms in nature, which was discovered by Sir Harry Kroto amongst others.
You can download the .mol file for C60 here, 
and then use it in Jmol running from your own computer,
and then use it in Jmol running from your own computer,Alternately, you can view the structure on this web page and you should be able to rotate and zoom the molecule.
C-2-60
This is the next structure in the C-n-60 series, in which 60 C60 molecules are combined to create a 'molecule' of 3600 'atoms'.
Once again, you can download the .mol file here, 
and then use it in Jmol running from your own computer,
and then use it in Jmol running from your own computer,Alternately, you can view the structure on this web page once again with the ability to zoom and rotate.
C-3-60
And finally, for now, this is a picture of C-3-60 which is composed of 216,000 atoms. The picture is a bit indistinct owing to the detail required. If anyone can create a better image and upload it please do so!
Here is the .mol file for C-3-60 
It's apretty big file, so beware. You may find that jmol fails to load this file as it requires more memory than Java provides by default (I had this problem on a Mac) It can be solved by EXPLICITLY giving Java more memory via the terminal.
If you fail with that you can give this file a go, 
it has 36,000 of the atoms removed and seemed to run OK for me.
