At my school we have this thing called the breakout box and there's a challenge. It's pretty hard, so me and some of my friends have been working on it. The idea is that there is a box with a bunch of locks on it and clues around the room to help unlock it. You have to use the clues to get the locks' codes - a 4 digit number - and open the box. So far we've opened every single lock except one. We've researched for about two days and we can't figure this out, so I decided that I would ask the online community.
The riddle is on the wall. There is this painting and we found out the painting is called 'The Woman and Bird in the Night'. It's by Joan Miro. (see below) The teacher who made the riddles wrote 'e=16' in the bottom corner on the white part of the paper. We aren't sure if this is a hint, a key, or something to throw you off. We really need help with this because we have unlocked all the locks except one. This is the only clue left, and the answer must be a 4-digit combination.
I'll be checking for answers about every hour.
Here is the picture:
Here is a link to a larger version of the painting if anyone needs it.
It might seem like this has many answers, but there is only one answer and it is a four digit combo that uses numbers. I do have access to the lock and every day I have been going down and checking all the combos that people have thought might be a possible answer and then adding a comment letting people know if anyone was right.
