I get the sense that there's quite a bit of humor embedded in these works. I don't understand most of the references, but there's one that I got right away.

Click the map of Italy. Roughly in the lower-right-center, there's what looks like a gray volcano. Zoom in and read the caption:

    Vesuvius

And just south of it:

    Pompeii (clausa)
    Pompeii (closed)
