These features may only exist in older versions of Minecraft, or were possibly never even implemented.
Gears could only be placed on the sides of a block. Placing them in a space where two sides are next to each other would cause the two gears to appear on both sides. Gears did not do anything, and they could not be obtained without hacking one's inventory. Placed gears were impossible to destroy. Any mining directed at a gear phased through to the block behind it, much like Water. If the block a gear was on was destroyed, the gear was not removed, but oddly, it would become invisible much like Barrier blocks. The gear still existed in the map, and it would show up again if the block was replaced. Gears placed in mid-air, through the use of a map editor, were also invisible, and they would show up if a block was placed next to them.
Gears were deemed to be removed from the game when their data value was taken by Redstone Dust and their sprites deleted from Minecraft's files. It is unknown what the real purpose of gears was, but it can be presumed that they would've done things similar to what redstone can do. Before Indev was removed, it was still possible to hack a player's inventory in order to get gears and place them. It is now impossible to obtain or even see the gear anymore without mods.
Whenever one changes the texture for redstone, the gear texture sprite will not appear and will be the black and purple unknown item block.
