Thanks guys. Jester: your 109 profile was what I was originally thinking of. I love it.
I tried Jester's technique of using the colours - below is 2 mins of plugging pixels to see the effect.
Adlabs: Thanks for the tip mate, it'll be a time consuming process if I go through and try to place each individual one. I need to add some more surface texture to my works generally so I'll experiment with some of the ideas you suggest.
Serval: I dont' think PSP8 has a bevel blending option on layers... i'll keep looking!
Thanks guys and keep the ideas and feedback coming!
