What's really going on with the Denver airport?

So I am bored at work (weird) and I didn't really have anything to say, so I decided to give conspiracy theories a go. There are many conspiracies surrounding the Denver Airport. I was at work last week and my  co-worker Brittany started talking to me about all the creepy weirdness going on, and I had to investigate! The first thing I found were the paintings which hang throughout the airport.
As you can see from the ones I've included, they are not your run-of-the-mill decorations...

There are tons more, but I think you get the idea. Also there is the evil blue horse guarding the front of the building...

Of course the theories don't end with just the artwork. Many architectural issues have turned up as well... There is a lot of buzz about the fact that the aerial and map views of the airport show a swastika.

Also there are a lot of problems and oddities associated with the building of the airport, The link below is for a site that has an in-depth history of this, as well as some other fun (or not-so-fun, depending on your viewpoint) facts. Enjoy!
