Mini gyro

Seiko Epson has come up with a 5 x 3.2 x 1.3 mm gyro sensor for use in anti-shake systems for digital cameras and cameraphones. They're cranking up mass production in December, so it shouldn't be too long before cameraphones get yet another step closer to digicams. We kind of hope they consider using the sensor for something fun like controlling games as well, though.
