Yesterday a French artist Pascal Boyard made an interesting announcement in his Twitter -
https://twitter.com/pascalboyart/status/1082082762180513793He painted a frescoe in Paris with a 0,26btc ($1000) puzzle in it. He will send these money to the first person who will pass the quest and find the code.
He also says that it's possible to do only standing in front of the drawing, but he added an HD picture to his tweet as he doesn't tell where to find it exactly.
Is it another reason to visit a Paris?

And I'm really interested how does the code looks like.
Same thing again and again. I saw some quest or riddle in the internet, tryin to solve it and fail, all the time.
