Trying not to be thick here, but from what I saw of the picture and from what I have read, but isnt this just basically an old LWMAX etc trick pulled into poser, eg. a series of layered sphere like objects that continually rotate to give the effect of a moving sky? - If so, I think its a bit much to ask someone to pay for a set of spheres. Then again, I never saw the attraction in having a curved plain for x amount of dollars (eg the cyclorama et al)
