Steins;Gate is my new favorite anime. It's about time travel and it even references Back to the Future.
It started out as a visual novel type game but I'm talking about the anime adaptation. The main character, Rintaro Okabe, is freaking nuts. He's obsessed with Dr. Pepper and fancies himself to be a mad scientist. He and his two friends perform odd experiments in their small one-room office / apartment / something, involving cobbled-together devices called "future gadgets". His friend, Itaru Hashida, is an experienced hacker who plays along with Okabe's craziness along with Mayuri Shiina, Okabe's childhood friend.
One day, while microwaving bananas (because why not?!), a chain of unexplained phenomena involving Okabe's cell phone and a girl giving a theoretical physics lecture suddenly turning up murdered - only to be perfectly fine moments later with no recollection of signs of harm - takes place.
The microwave, combined with Okabe's cell phone, turn out to be some kind of time machine. The story revolves around a "butterly effect" theme as events unfold.
It's a weird and somewhat original story with amusing characters.
I highly, highly recommend this show.
There are some funny coincidences with the studio being called Nitroplus and the title having the word "Gate" in it. Rest assured that this series came out long after I started doing 2214.
