designing a wall for a 10ft in -wall tank....looking for design ideas

[intarsiabox]

My personal preference is a just a regular wall painted in a dark color and having a dark wood trim around the opening for the tank. Tile, stone, etc makes the walls look busy and takes away the viewers focus on the tank. Dark colors will not reflect light in the theater room either. But in the end it's what looks good to the owner not what I think.
