Using the principles of the century old pin hole camera, also known as a camera obscura, these guys managed to turn a Parisian apartment into a movie screen. This is accomplished by putting shades over all the widows making the room completely black. Then by creating a tiny hole in one of the shades (you would use cardboard not a fabric window shade) to allow a tiny bit of light to come through, amazing projections will appear on the wall. Why does this work with just a tiny hole? That’s the magic of a pinhole camera. The people of Stenop.es are looking for more awesome locations where they can repeat the concept, so if you have a nice spot for this you can apply on the stenop.es website.
