I was just sitting at my desk at work waiting for my computer to reboot (10 minutes wohhooo!) and was reading the opening passages of a book called QED by Richard Feynmen, which got me daydreaming about gravity and entropy, and whether or not you could unify gravity by defining it as an entropically driven force.
So I get on the computer, and I google it. Major paper in Jan 2010, "Entropic Gravity", which I think is on the same concept

Which is kind of cool. I'm no physicist, frankly I suck at high end physics, and the whole concept of "entropic force" seems to be getting the same respect as String Theory. So it's not big thing, but it's still cool.
