The shape in this basement is pertrayed really nicely because it uses every basic shape all together and it doesn't look like they tried to hard to incorperate them in. The shapes in this basement make the room liik really big without it looking too empty. They have circular lighting and circular couches, but the cushins on the couch are squares and rectangles. The mini kitchen in the corner uses squares and rectangles in the cabinets and with the chairs around the circle table. Shape was used very nicely...I LOVE IT!!!
