Now that the missus and I have moved into a bigger place, I actually have room for a table! I've got a fairly decent terrain collection already, but I thought the table needed a few large LOS blockers too. With that in mind, I picked up some cheap vivarium ornaments and reappropriated them for the battlefields of the far future (where the only giant lizards climbing all over them will be ridden by exodites).
They aren't the same quality as the GW plastics, but they are cheap and super sturdy. I painted them grey, gave them a quick drybrush and a dip, and then they were ready to roll (after a coat of varnish).
