A couple of months ago, I was in a charity shop with my five-year-old son. He was digging through a big box of toy cars and pulled out an odd looking piece, which I think was meant to be a rocket of some kind. In the end, he didn't chose it as one of the two I had promised him, so I decided to get it myself. A bit of primer, a wash, and a harsh dry-brush later, and I've got a... well, I'm still not sure what it is, and that's why I like it! It could be a communications relay, a generator, a meteorological device, or numerous other things. It could be just some background scatter terrain or the focus of a scenario. Not bad for 50p and 20 minutes of work!
I've also added a couple recruits to my Colonial Marine forces - a basic trooper in his battle-scarred armour and a cyborg who has taken some punishment over the campaigns, but now serves as a heavy-weapons trooper.
