Rugs are great for inspiration.
If you've never stared at one long enough to see "images"
shapes created by whatever force, feet, natural movement, whatever, you wouldn't understand.
Anyway, I was trying to think of what a drone for a story i'v been writing would looke like, something mindless, bio-engineered. So I stared at my rug.
I saw a head.
A head turned into a torso, and my imagination did the rest.
Mind you this is just a prototype(and not anatomically correct either, haha), abut this is what i immediately came up with.
