My wife and I got married in 2015 and we wanted our wedding invitation to embrace my Swedishness and her Americanness. In the vain of never making anything easy on yourself, I figured it was a great idea to have the same invitation house two different languages. On top of each other. The card was sent out with a pair of stereoscopic 3d glasses. Just like the ones you got with the dinosaur magazines as a kid. If you coved your right eye, the invite appeared in Swedish. If you cover your left eye, it appeared in English.
