Check out this vidoe of Daishin Seiki's 5 axis mill carving a motorcycle helmet from a solid block of aluminum. Have to add one of these to my shopping list. The cam software is Hypermill. Want!

This guy does some amazing work with DIY CNCing. He's taken a $500.00 Harbor Freight mini mill first picture to the absolute limit with full CNC conversion including, power drawbar, 16 tool ATC, flood coolant  and tooling table check it out in the video below. Also check out hossmachine.info for lots of good DIY CNC information.

Pretty ingenious 3 servo design and it's arduino powered.

Pretty rare that I get totally stoked by an incremetal product release but this is too cool.

Researchers at the NanoRobotics Labratory at École Polytechnique de Montréal, in Canada have managed to control a swarm of bacteria using a computer to build a step pyramid structure. This particular type of microbe known as magnetotactic bacteria has an internal compass that can be influenced by a magnetic field. By manipulating a magnetic field around the bacteria they were able to create and direct the swarm. Best to check out the video which will make more sense.
