Most of the answers seem too obvious to list. I will say only that there is more to Swedish detective fiction than Stieg Larsson (start with Henning Mankell), lingonberries are usually a good idea in a meal, "Honey Honey" is the most underrated Abba song (it didn't make Greatest Hits I), there are more excellent Bergman movies than most people think even if you don't like the stereotypical ones, Carl Milles's greatest work is in a Fairfax/Merrifield cemetary on Rt.29 in Virginia, Emanuel Swedenborg is unreadable, and the world music group Simbi really does make note-perfect copies of native Haitian musical styles. The Cardigans are better than their reputation and Knut Wicksell's 1898 Interest and Prices still has unmined insights. The pizza is surprisingly good. Robert V. Eagly's book on the 18th century Swedish bullionist controversies is excellent and neglected. Everyone should read Staffan Burenstam Linder's The Harried Leisure Class. The country has long appreciated the merits of floating exchange rates. Ann Margret was from Sweden too.
