I saw this article a few days ago, I had about 100 different reactions, thought about reblogging it, but now I've decided it'll make for a good poll, even though it turns out the story is actually over a year old.
The guys that thought them up are artists (here's their site), so the idea was to make us think. And their robots don't do a whole lot, they're just a clock, a light, a coffee table (still no answers on what a coffee table is going do with all the power it generates), and two whose only function is apparently to eat flies. But the proof of concept is there.
Videos and poll after the jump.
