WordStreamer (aka MiniMuncher) is a speed reading tool. t works on the principle that our brains only process text when our eyes are not moving. WordStreamer simply streams a text file a set number of words at a time, at a rate specified by you. Since your eyes are not traveling from line to line and across the page, this allows you to read at a faster rate in no time by simply pressing up to increase the rate at which the words are displayed.
