Evernote is a cool idea.  They want to enable you to keep copy of all those random notes.  In this example I drew a quick sketch on an index card (on this topic).  I held it up to the little video camera on my Macbook and took this picture.

Then I dragged the resulting image into their application, and sychronized to their server.  Less than a minute later I syncronized again and they had run a bit of hand writting recognition over my sketch.  Not all, but some of the text was now searchable.

It works pretty well for business cards too.  Fun.
