After readin' up on ROBOTS and watchin' the film several times, i really liked the colour of the sky, it has a darker rich blue toward the top, and it fades into this nice crisp sky blue colour, which not only emphasizes a happy abode, but it gives a good sense of distance...so i did me own version, its not all that, but its a start, oh and i put it as a BG to one of the photo's i took.
