I used Graveyard Earth as the base colour of the sand, heavily drybrushing Kommando Khaki over that. I finished off the sand with a generous application of drybrushed Bleached Bone. This started my fascination with this colour combination. This was painted before the Foundation paints were released, so no Dheneb Stone introduced yet. I'd go on to use this paint scheme to paint up Necron Desert Stone Pillars which I'll probably put up some time soon.
For the glass, I wanted a shiny blue using white where the cracks in the glass where sculpted in and on the corners. I used Hawk Turquoise as the base, highlighting the edges with Ice Blue and further highlighting with Skull White. I then applied some 'Ardcoat to make the glass shiny, this was also just before Water Effects was released. The end result is okay, but I'm not entirely happy with it.
As for the use of the actual terrain, a couple pieces of it really adds nice visual interest to a board but it really doesn't affect the flow of play a whole lot. They're really no better than barricades. I find the best use for these pieces is for Planetstrike strategems like Crash and Burn.
