I'm currently in the process of thinking about how I am going to turn my bland study into an awesome uber-productive development environment. I want a place that inspires creativity, helps me focus and get work done. (this one is probably more up to me than the room).
I'm a firm believer that a good environment can have a big impact on work output. I noticed there was an interesting entry over at Creating Passionate Users which seems to confirm my beliefs. Check it out.
