Grinder Movement

The "grinder movement" are people who are augmenting themselves today, becoming real-life cyborgs.

Current Status
Today, some grinders have implanted neodymium magnets under their fingertips. This allows them to sense magnetic fields, such as those given off by engines.

Other grinders wear "EyeTap", which records all they see and can overlay data on real scenes, creating augmented reality.
