This is the principle that cameras use. Notice that all the images are upside-down, btw. Sadly, it will be really dark, there is no "brightness" button to adjust, but it's a cute trick.
Da Vinci was the one who made the first dark chamber, I think, in the renaissance. Most people think it was invented in the 1800. He actually managed to record the image on a huge paper attached to the wall, which I think is the world's first photograph.
This must be fake! The hole won't let enough light thru, for the human eye to notice a picture. Maby with a light sensitive camera, you can take a photograph of the wall. Or in this case, a light sensitive camera on time-lapse.
@LagArmy the hole in the paper becomes a point source from the light that is hitting it. It then projects this light in straight lines as light travels. i.e. the light from the sky travels down to hit the hole and then keeps travelling down to hit somewhere on the bottom of the wall, seeming like the sky is on the floor :D
does this work if there are two sources of light (i.e windows) that are not connected in the room, should i put a hole on both windows, or just one hole on one of the windows?
nope, nope, nope, nope, nope, nope.
