LOL!
Now you are going for an Escher-like interpretation! This is a kind of

I really like this image (and the previous) but it looks very aliased (and
the area light looks very grainy). Are you using anti-aliasing?

I am, but the high contrast messes it up, unfortunately. Maybe someone can
recommend better area light settings. I've tried up to 5x5 with adaptive 1 and
it still comes out grainy. Of course, the wall has some texture, which is
probably part of it as well.

A 5*5 area_light is very sparse. Try 17*17, 33*33 or even 65*65. It will be
almost as fast, only the penumbrea will take a little more time thanks to adaptive.
Whenever you use adaptive, increasing the density of the area_light usualy only
have a small effect on the render time.

Although POV-Ray 3.6 tends to have aliasing problems on the edges of bright
objects, the arrow of the exit sign has aliased edges but doesn't look too
bright. I wonder if you just need to decrease the anti-aliasing threshold?
If it's the 3.6 bright object problem, you could try rendering in version
3.5 or just rendering an extra large image and scaling it down.

The arrow been red on a dark background, there is about no difference on the
green and blue chanels. With only the red contributing toward the aa threshold,
yes, you need to decrease the aa threshold. A value around 0.1 should do the trick.
