The solution: A FOOH that transforms the urban landscape
To address this need for communication, we developed an audiovisual piece using Fake Out-Of-Home (FOOH) technology that simulated nature suddenly taking over Madrid’s iconic Puerta del Sol. In the video, a classic wooden Nature Trails sign crashes to the ground, opening a gap from which organic textures, earth and lush vegetation emerge, ultimately transforming the busy urban space into a temporary green oasis.
Technically, we achieved this narrative by integrating 3D animation with live-action footage. We used camera tracking techniques, dynamic lighting adjustments and physics simulation to ensure that the digital elements appeared fully integrated into the environment. Furthermore, we directed live actors during filming in the square to interact naturally with the virtual event, giving the piece the cinematic realism essential to maximise its credibility.


- Recreation of cracks in the tarmac, earthworks and plant growth
- Synchronisation (camera tracking) of the virtual elements at Puerta del Sol
- Visual storytelling specifically designed to hold the viewer’s attention in the first few seconds
- On-set direction to capture genuine and natural human reactions to the added digital event
Key findings
The launch of the FOOH campaign proved to be a resounding success in terms of viral visibility and engagement. By presenting the organisation’s information in a visually striking and highly shareable format, users acted as amplifiers of the message. The campaign not only captured widespread attention, but also successfully achieved its objective of strengthening the emotional bond between the public and Spain’s natural spaces.
In terms of brand positioning, the project established Nature Trails and the Ministry of Agriculture as pioneering organisations, capable of blending technology, sustainability and culture. The astonishing transformation of the Puerta del Sol demonstrated the tremendous potential of visual effects to modernise public communication, reminding the urban public that nature is within their reach through an unforgettable digital experience.
