One of the greatest things about animations is the freedom of creation. There are plenty great videos out there, and simply love surreal themes. Polynoid is a collaboration and portfolio of digital workers and they've done some great works.

Since there's no way to embed their videos here, I'm linking each one to its page at their site... and you should really take a look at these, cause it's awesome. I hope you enjoy it all! Cheers. ;)
