Seeing as how we're back on this thread, I should probably update as to what I've found too...well, ok, I'll only really mention one. FLCL. I swear, it's genius, even though it's nonsense. If you've played Guilty Gear XX, this is where the inspiration for I-No(the guitar-wielding witch boss) came from.
What's FLCL mean, you ask? Well, it's pronounced as "Furi Kuri"...but what's THAT mean? The most popular belief is that it means "Fooly Cooly", which somewhat represents the series well.. It can be completely idiotic one moment, then VERY cool the next. Also, it should be stated upfront that the series has VERY good music, done by The Pillows. It's good because it's so laid back..no matter what's going on. In fact, the main action themes are rather relaxed, which lends a bizzare feel to the sequences. Ones to get would be Sleepy Head(usually played during chaotic mischief scenes), Rush(played...for the hell of it, at any time), Little Busters(played when Naota kicks some ass of his own, even though it's a very slow and relaxed song), and I Think I Can(played during the final battle). Though I have to say, I'd watch the series before listening to the music; it makes a very large difference.
The series follows a boy in the 6th grade...but that's about all it really follows. Seriously, this stuff is bizzare... Haruko Haruhara, a self-called alien, appears out of nowhere on her Vespa scooter, pulls a ripcord on her guitar, and slams our young hero over the head with it. For no reason. This is just the first five minutes of the first episode folks; it only gets worse from here.
From there, robots begin climbing out of people's heads...one of which becomes a static character. Haruko demonstrates constantly how a guitar is a perfectly viable weapon; it seems to be able to stop just about ANYTHING.
The meaning behind the series is almost impossible to figure out immediately. Hell, it's possible there WAS no meaning to it. Though, personally I think it's about growing up, and setting your own goals rather than living to someone else's aspirations. Then again, I also think the moon is made of cheese, and that dogs are OUR masters. This series was made by Gainax, which is famous for the Evangelion series...another series with a cryptic meaning. There's a difference though; I HATE Evangelion. Its symbolism is completely meaningless, and it really doesn't do anything...FLCL however, entertains like there's no tomorrow.
Another strange bit is that Naota's father is a huge anime fan... He is constantly making references to other anime, and even does a bit of cosplay here and there throughout the series. Also of note, this is the only anime I've seen that has an entire segment devoted to South Park. For absolutely no reason, the art suddenly goes entirely South Park style... Don't ask me what it all means. I'm just the messenger, man.
E-eyebrows...
Edit: It's also worth mentioning that I've got a Haruko Haruhara wallpaper on my desktop...it's been there a while and it's not going anywhere any time soon.
