A basic clone of the Spritz speed-reading website. Their claim is that it is easier and more efficient to read text in a single location on a page. I'll let you be the judge of that.

Simply open main.html, put some text into the textbox, and click the button. The slider changes the speed of the text, ranging from slow to blazing-fast speeds. You may change the speed as text is running or restart before a piece of text is finished, if you wish.

If you are capable of reading at speeds higher than 720 WPM, simply edit main.html to increase the maximum value of the slider input and test your limits.
