Wondering what that $50 for a PlayStation Move wand gets you? Take a look at the chips and boards and wires inside the thing and find out.
iFixit, having got hold of one of Sony's new motion controllers, has unscrewed all the screws to be unscrewed, and catalogued everything they found inside.
There's nothing shocking to be found, though it's nice to know that the battery is easily replaceable should you run into any dramas. Oh, and that the LED light on the end of the thing is capable of 16 million colours.
