The company Grafftech has transformed several facades in Tarragona into interactive canvases. According to modernetdigital.cat, these 3D murals adapt to the viewer: they change shape and color depending on the viewing angle and respond to the movement of the public. It is not a simple graffiti; it is a digital layer painted over asphalt and brick.
How the murals that return your gaze work 🎨
Behind the effect are motion sensors and calibrated projections that alter the three-dimensional perspective in real time. Grafftech has applied a technique that combines physical paint with synchronized digital layers. As you walk in front of the mural, the patterns shift, creating the illusion that the figures are following you or reconfiguring themselves. It is not magic: it is code and acrylic paint working together. The installation requires no glasses or app; just move.
Urban art that forces you to put down your phone to look 📱
The best part is that, for once, technology does not ask you to take out your phone. The murals work even if you have your phone in your pocket or, dare I say, even if you left it at home. That said, if you stand still for too long, the mural gets bored and returns to being a normal wall. Neighbors have already started doing dance exercises in front of the works to see what happens. The city council, for now, calls it a cultural intervention.
