The sunday challenge = MACHINERY - "anything related to it" - may be old or new pieces of machinery. A piece of equipment with several moving parts that uses power to do a particular type of work. Would like to see the picture with the machinery as the main focus and without people if possible.

Really moving mechanical parts are the fan on the left, the CD-Rom station top right and the classical harddisk in the middle.

If you’re lucky to be an electron, this is the place to be.

The SSD station bottom right only swings electrons. But electrons really get in the mood at the CPU, the main processor at the bottom.
This is the interior of my computer. While I'm writing this, those electrons keep swinging at 3.2 GHz, a dazzling speed.
