+
+![Chaos Theory Gif](chaos-theory.gif)
+
+[Chaos Theory] is a tiny HTML5 game by [@necauqua] where you can draw and
+simulate pendulums with a few goals and restrictions per level.
+It was done for [Ludum Dare 49][Chaos Theory] with a help of a small custom
+engine with Rust being compiled to WASM and drawing shapes to an HTML5 canvas.
+
+You can play the game [online][chaos-theory-online], and the source code
+is available [here][chaos-theory-src] and
+[here][chaos-theory-engine-src].
