Everyone - Thanks! electroglyph - Great idea, but... I hate to think what the render time will be when I actually put it in a scene hehe TheBryster - you're absolutely right, it IS just the engine at the moment and isn't anywhere near finished Rayraz - thanks! - glass prism modelled in Wings3d (5 polys ;o) - the rest is primitives, except the curved arms which are lattices (which made the polygon count so high)
