At a minimum, getting things like this running does require:

1. An X server that supports the Composite extension

2. A compositing manager running to blend the windows (which may be
   part of the window manager)

3. A window manager that provides proper support for windows with ARGB
   visuals.

4. An application that achieves the desired effect by selecting an
   ARGB visual and rendering the desired shape into the alpha channel.

Have fun!
