Classroom theme?

For several years I did not do a theme in my classroom.  I had never really thought about it.  Then one of my coworkers was talking about her bug theme and how her students love it and how she had begun collecting all this very cool buggy stuff over the years and I started considering my options.  Then I decided to go with a movie theme in my classroom 2 years ago and I am still working on it.  This week I plan to make a second trip to my room to try and get some things up and take some pictures.  I am also really excited about the new things that I received in the mail from quill.com today that go along with my theme.

So my question is-- do you have a theme in your classroom?  If so, what is it?  Do you change it every year?  I know some people do, but with a little one in daycare, my husband would have a coronary if I tried to do that!  So I'll just stick with my movie theme for now and work on projects to make it more interesting. 

Comment below! Also feel free to post links to your blog posts on classroom themes or to pictures of your classrooms!  I loooove seeing other rooms in other schools.  Although I do get envious when I see STORAGE and BULLETIN BOARDS!  These are things that my school and classroom are desperately lacking!  All of my cabinets have wheels and my "bulletin boards" are just butcher paper taped to the wall or border put up to create rectangles on cinder block walls.  Sigh...
