I am going to be student teaching next spring

I have already begun to gather supplies for my classroom I am so excited !
I was wondering if any of you were teachers and if you had a theme for your classroom? Also, what was your favorite bulletin board? Your favorite art project? Your favorite "idea" of any kind that you want to share with a soon-to-be-new-teacher? Advice? Pictures of cool classroom stuff? Anything! I would love any comments or ideas or pictures you guys have
Or if your a parent, what was something cool your kids' teachers did?? A project, classroom design, communication, etc.?? Let me know what the good teachers do!!!!!!!

Thanks!
