It could only be obtained by inventory editing and was initially invisible in the inventory;[1] at some point this was changed to the animated version as seen when placed in the world.
When hacked into the game, gears could be placed anywhere, but would only display on the side of any solid block.
Placing them in a space where more than one side are next to each other would cause a gear to appear on all of the said sides.
Placed gears were almost impossible to destroy; any attempts to destroy a gear would phase through to the block behind it, much like water.
If the block a gear was on was destroyed, the gear was not removed ended up becoming invisible.
The gear still existed in the map and would show up again if a solid block was replaced.
Gears could therefore only be removed using a liquid to flow on them.
A gear's sprite consisted of two parts; the center rod and the animated gear itself.
