Spritz, a Word-at-a-Time Speed Reading App

I tried this odd little widget out and was reading comfortably at 500wpm, though I don't know how long I'd be able to keep it up. It's kind of like one of those brain-training games: difficult if you concentrate, easy if you relax. 

If it takes off, this would be perfect for smartwatches, Google Glass, and other tiny displays.
