Library of Babel - Weird. I like the minimalist design of this website. If nothing else you could use it as a soothing escape from all flashy, noisy websites that are always trying to get our attention.
Stuff You Do While Sleeping - Nothing surprising; I already knew about all of these but there's a really cute kitten at the top of the page.
Top Films About Time Travel - I have seen several of these. I'm not really a fan of the concept of time travel but sometimes it makes a good story.
Dr Alesha Sivartha’s Book of Life - Illustrations from the 1898 book The Book of Life: The Spiritual and Physical Constitution of Man
The Art and Science of Ernst Haeckel - WANT! But not at that price. (~sigh~ Sometimes being a cheapskate is hard.)
Miniatures - Everyone has been sharing this on Twitter and Facebook so you've probably seen it already but I just have to say, one more time, this is amazing!
