Colorful header with toys

I'm looking for a three-dimensional abstract background that spans the full width of 1323 x 270 pixels. It should feature an array of raised, overlapping squares and rectangles in various sizes, which create a sense of depth and shadow. The design must be in grayscale to emphasize the depth with shadows and highlights. Each shape should resemble a picture frame, clearly distinct, so photos can be added into each frame later. The overall composition should be clean, modern, and suitable for a professional website header.
