Thanks Heddheld - I'll try that tip :)

In that wall, each circle is actually in a hexagon... for reasons that, I expect are obvious, but may become clearer if I ever finish that model. But I think the same principle could be applied, with a couple more geometric calculations?

Yes, as Bill says, I've just "repurposed" the SA Kitty Mass Production figure that is shipped with Poser (think it appears in either Robots or Toys folder by default - I've reorganised my runtime folders so not sure).

I've simply re-textured him using some of BB's metallic paint shaders...
