Rustic Tiles (special print available).
This is made only by mathematical formulas, absolutely no manipulation. I deliberately put some noise in the rendering, in order to have a more realistic rustic feel (see the details below). Imagine a bathroom decorated with these tiles, totally nauseous!

These tiles look amazing, modern and vintage at the same time, well done. I will check the link right now:)
