Vintage genetics technologies. Old late 80's Cray Supercomputers, specifically something that resembles the Cray XMP. Old gene sequencers, research machinery shelled in a beige plastic casing and plastic wrap. Deep blacks in environments. Maybe a few state of the art, traditionally advanced science fiction material, but things that make sense. Think out interfaces, just like they thought out what the Nostromo would look like. Ron Cob it up a bit, but no too hard, allow distance from that, since it is much much later in the future than the Nostromo was built. Perhaps some kind of 3D Printer that cans stitch together cells and such, but not really as dangerous as that implies. I'm assuming, that The Alien has potential outside of weaponization. Perhaps bio-med, perhaps super-strong material, bio-plastics, there are possibilities. Maybe even using them as a basis for more weaponized synthetic that have a biological edge, genes grafted to a shape that doesn't resemble an Alien at all. A weaponized Alien is actually an idea that could work. Something that you have to eventually confront, given so much time in the series is to stop it from happening, I'm assuming Blomkamp is going in the way it is happening, so I'd hope that they make a design that is not just Aliens who are weapons, but more that everything is progressing past that.
There are some interesting ideas for the Bots in Elysium he could recycle for the Weaponized Synthetic using grafted Alien tissue and genetics, that still require a host in order to grow. Which would make the whole process more horrifying.
