I'm under the impression of tropical fruits. They have so unusual an exotic shapes and colors for my european eyes. I tried to minimize some of them (first the simple ones, mangos, avocados and papyas) after only photos. Although there are some types in the supermarkets in Hungary (I think they are only crappy, aftercured versions of the original, delicious fruits), I know them mostly in cans.
For the complicated fruits (mangostan, starfruit and the others) I have to invent the best methods before making them.
