I remember Amegas, and Crystal Hammer. Anyway, I've temporarily had to stop working on this because it was consiming FAR too much of my time. I was addicted to solving it and wanted to solve it but I everytime I seemed to be getting anywhere it would either fail or my head would go all fuzzy and distracted :-) I'll come back to it though as it MUST be possible, but no one has some definitive easy solution ... so far.
