perhaps you could add some "green" political figures, like Joschka Fischer and Ralph Nader?

I would like too. But: in Germany it can be a very very expensive mistake to use pictures which are not in the public domain...

As well as some others (see if you can guess my political beliefs from them... hah), like Fidel Castro:


Hugo Chavez:


Enver Hoxha:


Vladimir Lenin:
