Thanks for the input, folks.
Inky: You never seen the blu-tack shader? It's in
create shader>>>colour shader>>>blu-tack shader. 
Schmeerlap: You could probably swim it from there, Laddie! Jist roll up the troosers and jump in! Never mind the hanky!
I know this is a far from perfect recreation but I did only spend a night on it, as with everything these days. Very poor computer.
As an idea of just how poor a machine I'm working on: The above render, at the size you see it, detail=0.85, AA=8, GI=0, took me 21.5 hours, pitiful! And this is without the last row of render buckets along the bottom!
I rendered that part on my mum's machine... 2 minutes 50 seconds.
So, just for fun, I rendered the whole thing for comparison...
My pc = 21.5 hours(Still running, mind. I expect it would have been about 24-25 hours to complete).
Her pc = Completed in 1 hour 31 minutes.
I need a Lotto-win! I don't even play the lottery.
