Frog Queen, or the Prisma Engineering Headquarters (a machine and motor technology company) is located in Graz, Styria, Austria. Its facade was designed by SPLITTERWERK and looks like one giant pixelized box. Even the facade itself is practically a square. However, if you look very closely, you will see that each one of the pixels has circular patterns screenprinted on its face. Overall, the exterior features 10 shades of gray, and the square windows seem to blend into the rest of the pattern.
