Is life, in its most primitive form, possible in deep space?

Using physics, I cobble together a few vibrating arms, some steel balls and some chain to see if life is possible in the void of space. At its most basic level, I would think that movement would be one indicator though that might not be the only form of life out there. However, I'm imagining the creatures you see occasionally in Star Trek reruns, space creatures swimming in the cosmos.

So are the Star Trek space whales real? I've no idea, I'm starting with just a basic extremophile. However, after watching this video some of you may want to try building a real space whale and this video and Algodoo will do it. Algodoo is a free software platform that let's you play with physics. It's fun and that's really all I was doing.

I started earlier today trying to drain water out of a system in 0 g without moving out of your position. That turned out to be much harder than I thought as the system I setup to counterbalance the recoil from the water expulsion would force the system to move all over the place. I realized, even with such simple dynamics as vibrating steel balls on a chain, it may be possible to have life in the craziest of places.
