+# IntenseLogic Demos
+
+This repository contains several demonstrations of what you can do
+with [IntenseLogic](https://github.com/TheCodeLab/IntenseLogic).
+
+- Bouncing Lights: A heightmap with several bouncing spheres, every
+  single one is a point light source. The physics is performed by
+  Bullet Physics.
+- Shadertoy: A clone of the functionality offered by
+  [shadertoy.com](http://shadertoy.com/). Many of the uniforms are
+  provided. When you save a file, it instantly detects this and
+  reloads the shader while it's running. Detecting shader reloads is
+  performed through libuv.
+- Lighting: An attempt at demonstrating the physically-based rendering
+  pipeline in IL.
+
+# Dependencies
+
+- Bullet
+- SDL 2
+- libuv
+- libepoxy
+- libpng
+- tup
+
+# Building
+
+Just run `tup`.
+
+# Running
+
+The only one of these which really has command line options is
+shadertoy, which is invoked like:
+
+    shadertoy -f=some_shader.frag
+
+This will load any shaders in the shadertoys/ directory, which is
+where you should put any new shaders you make.
+
+You don't need to restart shadertoy if you edit your shader, it will
+reload automatically.
