It appears to be a jail door, considering the bars in the small window at the top. Perhaps it represents the wondrous contents within the game? Maybe it represents the wondrous contents of your brain once you have been properly enlightened by DROD?
It could also be a picture from the AE credits. I am only up to Level Fifteen, so that is pure speculation, of course.
Chances are that it was just a fancy picture Erik or trick drew that was put into the game simply because it looked cool.
