Japanese video-sharing site NicoNico Douga is well known for having its own unique net culture and memes. One of the most interesting of these is the "tegaki" style of video. "Tegaki," literally meaning "hand-drawn," refers to a type of video where a popular clip —usually an anime or video game opening—is altered to portray a different game or anime altogether. This is done by tracing the original source frame by frame, making the desired alterations, and then reanimating it.
