keybr.com | Typing at the speed of thought!: "Have you ever wished for a way to practice typing so that you may become a more efficient and capable keyboard jockey? Typing at the 'speed of thought,' perhaps? Enter Keybr, the flash based type instructor you've been waiting for.
Keybr is very straight-forward. You can choose from three basic lessons that start with a certain number of keys on the keyboard, and then, as you progress through the lessons, more keys are added to the mix to make things a little tougher. As a nice touch, it keeps live track of all your mistakes and your words-per-minute (wpm), and even creates graphs of your performance."
