Given that you can only see 3 sides, you could remove the vast majority 
of the boxes. Or you could do it with one box and an average pigment:

box {0.001, 0.999
    texture {
        pigment {average
            pigment_map {
                [1 gradient x color_map {[0 rgb 0][1 blue 1]}]
                [1 gradient y color_map {[0 rgb 0][1 green 1]}]
                [1 gradient -z color_map {[0 rgb 0][1 red 1]}]
            }
        }
        finish {diffuse 0 ambient 1}
    }
    translate -0.5 scale 2
}
