Nyan Nyan, widely known as Nyan Cat, became an internet sensation in 2011 after a YouTube video combined a pixel-art illustration of a cat with a pop-tart body and a catchy Japanese vocaloid song. The character flies through outer space, leaving a vibrant rainbow trail behind to the tune of 'Nyanyanyanyanyanyanya!' by artist Dan Busch. This meme represents the peak of early 2010s internet culture, often used to signify endless loops, adorable annoyance, or pure nostalgic joy. It has since evolved from a simple video into a staple of digital history, inspiring countless remixes, games, and merchandise across the globe.
