Spanish Artist Javier De Riba spray paints floors of abandoned buildings and segments of pavement to look like traditional Catalan tiling. De Riba also happens to be a member of Reskate, the Barcelona-based art collective responsible for the series of inventive glow-in-the-dark murals we posted about recently (click here to check them out if you haven’t already).

Like Reskate’s affinity for projects that have a deeper meaning, the state of the buildings De Riba chooses to work (and the contrast it creates) is often as striking as the patterns themselves. See more images and video below!
