Very fashionable, phluffy, breaks the ice at parties...

I sat through a prezi presentation recently. The speaker took us on a
long trip. It was "cool"! But in the end, there was not much to retain,
and I thought: "where's the beef?".

As to the constant zooming in and out, I kept wondering what the little
specks represented (that I knew we would soon be visiting). Sort of like
the old transparency technique of hiding parts with paper flaps. Lots of
suspense! :)

Remember, viewed from afar, all organisms look just like flies.
