Rocks and stones are natural formations of minerals that can be used to create the most primitive [technology](technology.md). Stone age was the first stage of our civilization, characterized by the use of stone tools. Rock [nerds](nerd.md) are called geologists.
Rocks are pretty [suckless](suckless.md) and [LRS](lrs.md) because they are simple, they are everywhere, free and can be used in a number of ways such as:
- For [fun](fun.md) and entertainment, you can play various [games](game.md) with rocks: rock skipping, petanque, long throw, [marble racing](marble_racing.md), even [chess](chess.md).
- As a [weapon](weapon.md), even though we discourage this use.
- For writing, some can be used as a chalk, some may be used to carve into, which makes rocks an extremely durable storage for both [digital](digital.md) and [analog](analog.md) [data](data.md) -- thanks to this we have records of very old [history](history.md), see also [RCBD](rock_carved_binary_data.md). A dust from some rocks can also be used to make dye to paint or write with.
- To make [art](art.md), decorations, small statues etc. Some rocks are beautiful just by themselves and autistic people like to collect them.
- For breaking things, cutting, grinding, sharpening etc.
- With a little advanced technology we can get metals (and potentially other material) out of rocks, extract geological knowledge from them, read records of prehistoric organisms (fossils) etc.
- They can be shaped into many more things like bowls, plates or maybe marbles which in turn can be used e.g. in some kind of [mechanical computer](mechanical.md).
