I looked right at that logo the other day and did not notice that same UFO outline pattern... I've seen it in two other spots...
I think there is some minor purpose for this... I also noticed the same pattern in the fountain with the eye sculpture at the Koltz center. Maybe its to confuse us or to draw our attention to some detail that will lead to a clue.
Its most likely little clues like this that will eventually lead to the solving of whatever this easter egg/mystery is.
The best thing is most of the people here will be focused on harping on the same old stuff while people who are looking at the little stuff that is cumulatively more obvious and compiles to build the final keys to solving this.
Thanks for the pix.
FYI- Looked into who or what Arcadius was... He was a weak Roman Emperor of the Byzantine half of the Empire... from 383 to 408 AD...
Totally not who I thought he was... and as far as I know there are no myths or legends attributed to him... basically he was a boring chap dominated by his wife's influence.
I was hoping he was rumored to have had an ancient greek jetpack or something... stupid lousy Byzantine Empire and its lack of hidden alien technology.
Sorry to have to debunk you man, that was a good spot, but the arcadius logo is a hexagon, and the UFO is an octagon
