3. The first giant fullerene C240 built originally just for fun
with Ken McKay Nature 1988

4. C with Ken McKay

5. The larger they get the more obviously icosahedral they become

6. In the electron microscope we see the contour

7. Left: Simulation Right: observation
Electron microscopy yields cross-sections and we explained previously not-understood structures of certain common carbon shell particles

11. Computer simulation of an electron microscope image
with Ken McKay and David Wales 1988

15. All the curvature is localised around the red pentagon

16. The surface is almost flat between the pentagons

18. Fuller has adjusted the strut lengths around the pentagons distorting the hexagons to produce an overall spheroidal structure

19. In the electron microscope we only see the shell contours

21. This led to the first explanation of the structures of the non-spheroidal structure of onion-like carbon particles
