-Demonstrate the use of `Camera2DManual` for manual camera control.
+Demonstrates how to use `Camera2DManual` to have

-The application is configured with a 720x720 window size. Within the program, a custom camera (`Camera2DManual`)

-Three circles are drawn on the canvas: a small pink one, a medium white one and a large pink one.
-Only the pink ones are affected by the interactive `Camera2DManual`, while the middle white circle is outside
-the camera's isolated scope.

 ### DemoParametricOrbital01
 
+Demonstrates the use of a `ParametricOrbital` camera.
+This 3D camera can't be directly interacted with a mouse or a keyboard,
+but only via a GUI (or via code).
 
+The GUI state is saved when closing the program and loaded

+The GUI also allows randomizing, loading and saving

 ### DemoAside01
 
+Demonstrates how to reuse a layer in the Compositor by using `aside { }`.
 
+The `aside` block can make use of `draw`, `mask` and `post`. In this demo
+only the latter is used to apply a full-window animated `Checkers` effect.
+The `aside` is not displayed by default.
+
+Next, a white, centered circle is drawn.
+
+Finally, a `HashBlurDynamic` post-processing effect is applied. The dynamic
+version of the HashBlur effect multiplies its `radius` argument by the red component
+of the provided texture (containing the animated checkers in this case).
