I found this great lenticular 3D postcard yesterday with an interesting juxtaposition of science and religion. The writing on the back reads:
The funny thing is that there really is a thing called The Astronaut’s Prayer already. It’s been rumored that Alan Shepard uttered “Dear lord, please don’t let me fuck up.” just before becoming the first American in space. I would have loved to have seen that scribbled on the back of this card in some calligraphic font.
