Neal Agarwal has given us plenty of games and web toys at Neal.Fun (previously at Neatorama), but this one takes a left turn into just plain fascinating. Size of Life is a slideshow that compares the size of living things on a scale from strands of DNA to to largest living thing on earth (you might already know what that is). Of course, not every living thing can be included, but there are some surprises along the way, like a jellyfish with tentacles that can grow 100 feet long, an extinct armadillo that was bigger than a bear, and an entire animal that's smaller than our white blood cells. Although I would argue if that orangutan stood up, it wouldn't fit between a crab and a penguin.
At the bottom right, there is a button that lets you compare the size of any two creatures in the show. However, if the difference is really big, you'll have to use an arrow button to see them both, and you may have to look really hard to see the smaller organism. -via kottke
