Wonder of Wonder Art refers to a viral web-based interactive animation created by the Japanese artist and developer Danmaku. Originally launched as a playground where users could watch characters dance to a rhythmic, upbeat track, the art style is characterized by its bouncy movements and expressive, wide-eyed character designs. It gained massive popularity on platforms like Twitter and TikTok, where creators began inserting their own original characters (OCs) or famous anime icons into the dance sequence. The meme represents pure joy and rhythmic energy, often used to showcase character designs or simply to share a positive, 'vibin' atmosphere within the art and animation communities.
