My daughter drew it and I agreed to build it.  She's an Artieeeest you know.  Here's the result:

BTW, that book on the bottom left is a faux book.  I took a worthless antique book and cut out the pages except for the very top.  I then replace the innards with a 2 x 6 and attached it from below with deck screws.  The entire back wall is a false wall a little more than 2 inches off of the real wall.  That's the only way I could support the weight at the funny angles she wanted.
