IconSpeak is a useful T-shirt with 40 universal icons that you can just point to when traveling abroad. Although there are plenty of apps available that you can download to your iPhone or Android device, sometimes it helps to have some basic icons readily accessible to help you get your point across when you don't speak the language. The idea was conceived by three Swiss travelers after their motorcycle broke down somewhere in Vietnam, which you can read about in their blog.
Many times we were confronted with a language barrier that was only to be overcome by drawing signs, symbols or icons on a piece of paper, map, or into the dirt. We thought it would be great to have an essential set of icons with you, permanently, so that you could just point on whatever you need – and people would understand. Soon the notepad was pulled out again and we started listing more or less essential icons that would have been of great help during not just ours, but basically anyone’s trip.+
