Ambassadors might be requested to produce some live USB media during an event.
Here are some artworks that one can print to make their own live USB station.
It's written in French, and basically means « bring us your USB stick, we take care of the rest ». Visitors are suppose to plug their USB stick in between the two arrows where we made a hole and placed a USB extension to the computer creating the live media.
SVG sources and photos of the finished station are available in Carlos' Fedorapeople space.
