Wearable words
Aside from a real tattoo of the Philae comet lander, what better way to show one’s love of science and exploration than by a temporary tattoo of Charles Darwin’s tree of life? Lithographs.com offers the removable skin art for just $5. And if a tattoo isn’t enough to fully express your loved one’s zeal, the website also sells T-shirts and tote bags smothered in text from Darwin’s On the Origin of Species, Opticks by Isaac Newton, and other books. As an added charitable bonus, the company donates a book to a community in need for every T-shirt or tote it sells (and for every five tattoos).
