Time Machine

While browsing, I happened upon Ponzo's Time Machine. Intrigued, I checked it out and find that the "Ponzo" referred to is ... ME! Huh? A time machine? Once upon a time I wrote a spreadsheet that looks for a historical month that matches the most recent month ... then asks: "What happened, in the past - and what might happen in the near future?" I now realize that (surprise!), I got me a TIME MACHINE! The author of the above article goes a step further. He identifies the five best matches and projects them all to see what might happen in the future. Delightful! Why didn't I think of that?
