SEIKON certainly is no stranger to the Polish streets of Gdynia. Therefore, we figured it would only be a matter of time before the Polish street artist left behind a little something for Traffic Design Festival.

Similar to his past work, SEIKON's latest mural considers the architectural components of his canvas. His signature geometric shapes and lines mesh and blend in with the building's windows. In fact, it's almost an optical illusion of sorts. At first glance, the building looks ultra futuristic, boasting a disarray of odd-shaped openings and lines. Then you look closer and realize it's another piece from one of Poland's finest.

Up next are murals from street artists Elian, Pastel, and Sten & Lex, so be on the look out. There's a lot more to come before the festival ends June 28.
