Boeing has done this before when they needed to make a long test flight but didn't have to go anywhere in particular for it. If you have to cruise around for X hours and end up back where you started, may as well trace out an amusing shape while you're at it. This looks like some sort of Airbus test flight so probably the same idea.

Anyone know the reason for this? To promote this website? :P

Test Flight (probably acceptance flight) of A380 for Emirates. Started and landing at Airbus' factory in Hamburg.
I assume it's a test flight....other wise it would a very expensive thing to do
Well it is still a very expensive thing to do :)
Well yes, but not testing an aircraft and having it crash and kill people is likely even more expensive.
