The Dissident Frogman is actively maintaining and updating a blog entry with "Support Denmark" graphics in multiple languages. Translations in additional languages are forthcoming (Traditional and Simplified Chinese, Japanese, Farsi, Arabic, Vietnamese, and Korean, to the best of my knowledge.)
Oh, yeah: go out and stock up on Havarti cheese... it's not only a show of support contra the recent Islamist boycotts and violence against the Danes (and random others in their neighborhood) but it's also damned fine cheese.
