I don't have pics, but a girlfriend of mine has a similar wall layout. She has a tall plant/tree grouping at the tallest corner (hers is wood so slightly different aesthetic). One of her walls continues straight from the corner, and the other tapers. On the tapering wall she has a shelf mural holding pieces from her cremaware collectionwhite china collection (think Potterybarn-esque, like this. The straight wall holds artwork her son painted for her - kitchen herbs planted in white china tureens - with a few more pieces of the china scattered. Opposite she has a "Something's Gotta Give" cream beadboard display with white china.

It's not my taste at all, but it looks very pleasant in her space. I'll see her this weekend, but no promises that I will remember my camera. :)
