Video: Jacob Applebaum: To Protect And Infect, Part 2 [30c3]
The following video details many different methods that the NSA monitors computer communication. All the way down to entering your house physically and making modifications to your computer. Jacob Applebaum has had his house broken into by NSA most likely as a method of intimidation as it is highly unlikely he is a material threat.

Gyro Cube that would that never needs Euler-ed
Notice the low speed wheels that do the balance compensation.
The Cubli is a 15 × 15 × 15 cm cube that can jump up and balance on its corner. Reaction wheels mounted on three faces of the cube rotate at high angular velocities and then brake suddenly, causing the Cubli to jump up. Once the Cubli has almost reached the corner stand up position, controlled motor torques are applied to make it balance on its corner. In addition to balancing, the motor torques can also be used to achieve a controlled fall such that the Cubli can be commanded to fall in any arbitrary direction. Combining these three abilities — jumping up, balancing, and controlled falling — the Cubli is able to 'walk'.
