Sam and I played a game of 40k last week. We really need to get moving on the terrain. The coffee-jar lids stacked up will make good sci-fi towers, I think, when they're glued and painted to look like cement. And the yeast tin should make a good oil tank. We have a bit of fence/barrier that needs finishing. And some cone shaped things that need to be painted too. Lots of stuff, none finished. I'm trying to avoid the typical ruined gothic manufactoria that seem to litter the 40k universe.
