Face Painted With Blood From Mosquito
As part of an ad campaign for the mosquito repellent, “Glorix”, a Russian ad agency filmed an artist crushing a blood filled mosquito on a wall and painting a miniature face with the blood. One result is a series of tiny images that require magnifiers to view the details. The images and video (with an annoying flying mosquito in the sound track) were not only used to promote the mosquito repellent, but also to encourage blood donation.
