Thanks tarquion, I think I may have read that book many years ago, I read a lot but not so much the sci-fi these days. But did go through an Asimov and A.C. Clark stage about 15 years ago! I've added more bits and pieces since that render but you'll just have to wait to see that! I can say I'm quite happy with it so far though, just can't believe there's only a week and a bit to go, it's flown by...lol I'm really looking forward to seeing everyone's entries.
