Idea is ok but perhaps you want to reconsider your technique. Right now the only way to see the dancers is via SBS, the lines are very hard to see in the final entry. What if, instead of drawing lines yourself, you use the curly (almost dancing lines from the glass structure? It's maybe a bit of a puzzle with selecting the parts and put them all in a logical way so the dance figure appears, but I think the effort would be certainly worth it. Good luck!

Idea is great, execution needs more work though as waz has suggested.

Thanks, I'll see what I can do

K- I played with the layer settings for half the day - think it looks better?

You can definitely make out the dancing form s a little better now.

thanks mad, but I think the 'magic' of the first try is lost...
good that I have a copy for my own desktop
