Walk a little farther down the road, and you'll bump into Casa Mila, the mother of all geometrical middle fingers:
Its wave pattern is gorgeous, but only sailors could live there without projectile vomiting all the time.
The reason Antoni Gaudi, the architect behind these projects, was able to turn his genius yet impractical doodles into actual buildings for people to be in was the same that enabled most of the famous classical composers to do their thing: He had a rich patron. Industrial tycoon Eusebi Guell was a huge fan of Gaudi's work and happily threw money at his projects in a way that would make even the most adventurous venture capitalist go, "Whoa, dude." Gaudi kept filling Barcelona with stranger and stranger constructs, inspiring many other architects to adapt his nature-inspired, angle-hating style.
As a result, it's difficult to walk around the older areas of Barcelona without getting the creeping feeling that a fat plumber in overalls is going to start battling Goombas in front of you at any minute. Nowhere is this more evident than in Park Guell, Gaudi's large-scale landscaping project that turned a large park area into a full-scale video-game layout of different areas (levels) that look completely unlike each other. Feel free to Google pictures and see if you can find a suitable stage for each Street Fighter character. Meanwhile, here's the statue guarding the whole area.
Yes, of course it's an LSD dragon. I don't know why you even bothered asking.
How To Turn It Into A Movie:
Park Guell and Sagrada Familia alone wouldn't look out of place in a live action version of, say, a particularly deranged Nickelodeon cartoon. Then again, these places are easily awesome and deranged enough to use in a very particular movie fantasy of mine, one I've ranted about before. So, look at those pictures, friends, and say it with me:
Fuckin' Psychonauts movie.
