I stumbled upon this rather interesting bit of software, Nanorex allows you to design nano scale machinery and run simulations of how the stuff would work. Nano-scale machines may one day allow us to do all sorts of interesting and fun things. The best possible option is that one day we all have night vision and can jump over buildings in a single bound…or perhaps we could use them to cure illness if you are into that sort of thing.
