A working camera that lives in a pop-up book.
From her site:
For the past couple of months, I’ve been searching for the right sequence of cuts and folds to turn a piece of paper into a camera. Specifically, I wanted to make a working camera within an educational pop-up book—one that connects the dots between design and science / structure and function. Happy to report: it is finally real! The final book explains—and actively demonstrates—how a structure as humble as a folded piece of paper can tap into the intrinsic properties of light to produce a photograph.
As far as 1800’s tech goes, pinhole photography is an great example of material acting as more than the sum of its parts. If you’re in the market to be blown away by something you normally ignore: make one over the holiday. You don’t need this book—all that you need is a lightproof box with a hole in the front (mini-hangtag safety pins yield a perfect 0.3–0.4 mm hole) and some light-sensitive material loaded in the back. The results achieved by such humble means is a feat of true cosmic piggybacking—showing that objects we make (even from the most lo-fi materials) can be structured to tap into impressive forces at play in our world.
