As PBL07 we decided to individually re-create a poster we had as teenagers. I have to say that I was not allowed to stick any poster in my bedroom, but I survived without any trauma :)
The only poster that, without any special enthusiasm, I have been allowed to put on was a photo with a forest with the sunlight filtering in through the trees ... quiet and relaxing ... not exactly like me when I was a teenager ;)
Here is the poster I re-created trusting my memory and moving beyond...
