How funny, when I looked at the pics I didn't even think about messy rooms, I thought, how wonderful to have so many great things! My stash is still very puny, and I'm jealous!
I know you said the room is only like this because of recent activities, but some creative people just don't do as well when everything is straight lines and closed boxes. When I'm planning a quilting project I'd much rather have things in heaps on the floor around me than in neat little stacks on a shelf.
That said, when I work (software testing) I only like straight lines and, frankly, white walls. Everything has to be in its place. Go figure.
Just wanted to point out that sometimes there is real method to what others may perceive as madness. ;)
