15. WolframAlpha's Handwritten Knowledge Engine
Handwriting is a skill many seem to be forgetting in the digital age, but WolframAlpha is reigniting its passion for an art that has been with written verbiage since language began.
The WolframAlpha Handwritten Knowledge Engine will — in realtime — regurgitate results from its existing pool of information and spout it back on your screen by a "real person" handwriting your results. Of course, they're just kidding but it's got some interesting results.
Try it here.
