Brill. How about positioning some low shadow mapped spotlights in the ceiling and pointing them downwards, and texture bumps - open a small document in Photoshop or whatever 200 x 200 px say colour 50% grey and add noise, you'll get highlights and lowlights and can apply this as a tiled texture to the mats. Hope this helps and as I am grouting the bathroom at the moment I can only agree with Robert on how we europeans like our walls. Hope to see more Oliver
