As writing tools go, WriteRoom is about as basic as they get. By default, you get green letters on a black background (see below). I mean a black background — the entire screen goes black, with just a green flashing cursor awaiting your typing.

As you might know WriteRoom is a writing tool for Mac that sole purpose is to help the writer focus on his/her writing. It features a plain basic text view without any disturbance in a form of chat window, e-mails, twitter, and others.

I wrote this blog post using WriteRoom, and it helps me focus on writing the post (rather than switch between Safari tabs)

For Windows user, you might try Q10 that had a similar feature like WriteRoom. Write on.
