@carvl Hi Caroline - thanks for having a look - I loved the textures and shapes and perspective but I have to admit the colours are produced by using a negative effect. It was so much more interesting than the basic combination. Cheers Rob
@kali66 Hi Kali - It's very nice to know that you liked it - it's a bit weird but I really liked it too. I'm not sure I know what agate looks like when cut across - but from what you've said it must be worth seeing.
