That's your ceiling.

As in, not your roof.

You're not OP.

It's called a Camera Obscura.

Artists from yesteryear used them to draw accurate copies of real objects.

PS. I would be tempted to never open my curtains again.

English not as a first language, my friend.

I'm British, but I have lived in the middle east my whole life (including the past 7-8 yrs in Dubai). English is in fact my first language.... I'm just shite at it :P mystery solved!

I did this in my room a few years ago, it's really cool. Here is a picture.

Indeed

I've never seen this in person, and every time I see it on the internet it seems so strange.

It still confuses the shit out of me today.

you can't tell by the picture, but the projection takes up the whole ceiling. I'm guessing it is due to the horizontal arrangement of the shutters and the vertical orientation of the slit between the curtains making a perfect pinhole. probably never going to happen again!

That must have confused the shit out of people back in the day

google 'pinhole camera', it is very simple to make and is one of the most basic optical instruments :)

yeah reddit is weird sometimes

There was an awesome special on HBO about Vermeer's paintings using a modified Camera Obscura. Great watch if you can find it.

My aunt's a professional pinhole photographer:) I'm currently travelling around France and Belgium with her assisting her in a project that she got a grant from the Canadian government for, shooting old ww1 battles sites - specifically those involving Canadians. Quite keen to see the finished pieces.

It's interesting since this principle was first demonstrated in the middle east as a form of entertainment for the sheiks and whatnot.

Hey as a kid i remember our teacher told us to cut a hole in a cardboard box to see the solar eclipse that day. Now i guess that is the same principle.
