"A company at a German trade show has attached tiny banner advertisements to flies and set them loose on unsuspecting visitors, in a bizarre yet effective marketing stunt.
The banners, measuring just a few centimetres across, seem to be causing the beleaguered flies a bit of piloting trouble. The weight keeps the flies at a lower altitude and forces them to rest more often, which is a stroke of genius on the part of the marketing creatives: the flies end up at about eye level, and whenever a fly is forced to land and recover, the banner is clearly visible. What's more, the zig-zagging of the fly naturally attracts the attention because of its rapid movement."
