From the John 10:10 project at Vimeo:
Enter a living human cell to discover a world of unimaginable precision, complexity and design. Measuring less than 2/1000th of an inch in diameter, the cell is packed with molecular machinery that makes life possible. These microscopic wonders include our DNA – the genetic code. Through extraordinary computer animation you’ll discover how the more than 18 trillion feet of DNA in your body is organized, stored and processed.
Imagine, all that information in there doesn’t weigh anything. But it matters.
