I've used POV for a long time, but I find lighting to be one of my biggest
challenges in scene development.  I thought it might be interesting to get some
examples from the community on creative ways to light a scene:

Below is a primitive scene (no pun intended) with only a basic light source.
With the restriction that you aren't allowed to change the camera or the objects
(including their mundane textures), what creative lighting solutions can you
come up with to make this image more interesting?
