A company at a German trade show attached tiny banner advertisements to flies and set them loose on unsuspecting visitors, in a bizarre yet effective marketing stunt.
"One marketing creative's stroke of genius is another person's animal cruelty."
The banners, measuring only centimeters across, seemed weigh the flies down. This forced 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. (via Kottke)
