The challenge was to manage to perfectly play the "trompe l'oeil - optical illusion". Having clearly a reference of microscopical view of the blood at first, and clearly corks and plugs in a second time. To do so, we did various versions of the corks in 3D.

We decided also to use the DOOH in a way that it looks like an animated print. Only the image of the corks zooms in. To create a moving surprise for the viewers.
