* Basic summary of Langcraft.

It's probably too long, and it needs a cool picture.  Hmmmmm.

* Try to shorten and combine author's feedback.

* Remember to add Langcraft repo link

+### [Langcraft]
+
+[Langcraft] is the Minecraft LLVM target you've never wanted.
+
+Langcraft started as a dare to the `#lang-dev` channel of the Rust
+Community Discord to be able to parse Rust code in Minecraft.
+Naturally, it grew into a full code generator that can translate
+most LLVM IR to
+[Minecraft data packs](https://minecraft.gamepedia.com/Data_Pack),
+the game's deliberately-limited in-game scripting language. Langcraft
+is entirely language independent, so any language with an LLVM-based
+compiler can (with the right API bindings) run in Minecraft. Currently
+bindings to both C and Rust exist. While not as visually impressive as
+a redstone computer, Langcraft does stretch the bounds of the game quite
+a bit, using jukeboxes for memory, armor stands to represent pointers,
+and rearranging compiled code to make it run in the bounds of the data
+packs' fixed instruction limit.
+
+This is all, naturally, entirely useless. The project is also still
+heavily work-in-progress and does not pretend to be stable, but it is
+usable. A handwritten interpreter for a Rust-like language has already
+been demonstrated running, and even more complex projects like [CHIP-8
+emulators](https://github.com/Dhole/chip8-rs.git) function (albeit at
+extremely slow speed).
