A fish swimming through Vienna.

Found along the Danube Canal, this hand-drawn mural turns an ordinary concrete wall into a little underwater world. With confident black lines, a vivid green eye and flowing fins, the fish seems almost alive, quietly drifting through a city better known for imperial palaces than street art.

The beauty is in its simplicity. There is no attempt to hide the wall beneath it. Rough concrete, chipped paint, cracks and weathered marks remain visible, becoming part of the drawing rather than something to cover up.

And perhaps that is what makes it feel so at home along the canal. The walls here are constantly changing. New works appear, others slowly disappear beneath fresh layers of paint. You never quite know how long a piece will stay, which makes finding one feel a little like a fleeting encounter.

When translated into textiles, the fish never stopped swimming. The flowing fins and rhythmic hand-drawn lines move naturally across the fabric, while the weathered textures bring a little of the original wall with them. The bright green eye remains, of course, quietly keeping watch.
