Good Questions: What Should I Do With This Alcove?

Hello Design Gurus - Attached is a picture of the strange alcove/shelf in my new D.C. apartment. Any ideas on what I can do with it? It's a bit high and small to fit a TV, and somewhat deep to function as a bookshelf....

(Note: Include a pic of your problem and your question gets posted first.)

I should also mention, it's a rental and I'm not allowed to paint. I am perplexed. Please send suggestions!

Thanks! Libby
