Nothing much to see here, just a cat with a Pop-Tart for a body. That flies through the air. And shoots rainbows out of his furry butt. To an upbeat synthesized pop song. Whose lyrics are "Nyanyanyanyanya" – the Japanese version of "meow." Yep, nothing much to see here – except nearly 50 million have, indeed, watched Nyan Cat on his spacey adventure.
