Ferrofluid, basically its tiny iron particles suspended in a liquid.

But man does it make for an alien experience. Kinda creepy the way it makes spikes. BTW, I assume this is very similar to the technology behind magnetically adjustable shocks.

not so cool version

they are working on this technology for use in adaptive body armor.

There's a company with a similar concept and and already working suit. Not sure if its similar to ferrofluid, but it hardens on shock/impact, but is otherwise loose and flexible.

Crazy...for about a minute.

I was reading this awhile back, i heard they are working on it, but a working prototype, I'd like to see that.

D3o is based on foam/rubber. It was in Wired, which is where i've found it. But its working. Probably a very different technology than the ferrofluid.
