There are several levels of tidiness: tidy, very tidy and totally deranged tidy. 

The swiss artist Ursus Wehrli is placed in this last category. He's a man of obsessive order, as he demonstrates with eye-catching surprise in The Art of Clean Up: Life Made Neat and Tidy. 

Have a look at this book. Everything is so beautifully organized!
