Eichborn - Banners on flies (for real) - ambient, Germany

Jung von Matt just invented flyvertising. At the recent Frankfurt book convention they attached banners to 200 flies and set them loose to do their jobs as miniature sky ads around the convention center. In German, it's called a Fliegenbanner. Fliegenbanner, what a silly word.
No flies were harmed during this stunt. But a lot of people laughed.

The weight of the banner itself, attached with a string and some sticky stuff that allowed it to eventually fall off without harming the fly, was so that the fly could fly with it, but not very high and they kept landing on visitors. Do flies get short of breath? Client: Eichborn
