Nyan Cat

I have no idea why this is popular.  I saw this random image of a random creature that was half pop tart and half cat flying in space on several websites on the Internet, and after a little searching I found out it was called Nyan Cat.  I then googled the website, expecting a funny video or at least something mildly entertaining, but that's not what I found.  Instead the YouTube clip that is just this weird cat/breakfast pastry flying through space to the sound of techno music.  That's it.  Nothing else.  I thought that because this meme was so pointless it would go away, but it's still going strong on the web.  It now has over 40 million views, and has tons of iterations.  I've posted a few below.  It even has an entire website dedicated to the meme.  I hope this dies away soon, but it doesn't seem like that's a possibility for a while.
