I had a thought that what you could do is make a large puddle, then get someone to put in sticks for each star, guided by a viewer.
I'm with you 4W, I don't see any reason why not, and if the other alignments are correct, then it would tend to support the theory.
Of course, all this obviously points to memorys of a distant advanced civilisation that came here from Orion but were subsequently wiped out by a natural disaster ;o)
