I recently came across the Powers of Ten Flipbook, a wonderful odyssey in to the world of remote sensing. I can't say it better than the product description;
"Based on the best-selling classic Powers of Ten, this magnificent journey begins one billion light years away, with every two pages representing a view ten times larger than the view two pages earlier. As readers flip through the pages, they will descend the dimensions of the the universe, through our solar system down to a park on earth, then into the human body, its cells, DNA and finally a single proton. A fun and compact visual odyssey, The Powers of Ten flipbook shows us not only the relative size of things in the known universe, but also our place in it."
Really puts a new perspective on things!! And, of course, what I didn't realise when I saw this was that this was based on the original 1971 movie (and by the looks of things an earlier B&W version). Play it below.... well worth the watch.
