It's an Alien Pumpkin sort of thing

Here is one some may have seen before.  The alien looking in the window with the pumpkin carved just like it.  Well last couple of nights I have laying glowing paint on it.

Here is a "simulation" of what the "glowing" paint looks like. Since I could not get a camera shot I made a fake. So this is sort of what you see when the lights go out.
