I like the different textures of the image inside the "window." Some appear to be looking through frosted glass, while other areas are clear. I also really enjoy how the dark of the window and the bright, extreme contrast of the outside really play on each other. Oh, and the lighter parts of the image are all brain scans. 

As with all pieces, they are printed on aluminum with  a floating hanging system on the back. Extremely bright, beautiful, durable and need no expensive matting and framing.
