Anyway, I put together a simple statistical simulation (still a work in progress) that lets you run experiments with how long it might take your numbers to hit the jackpot. It's on googledrive here.

The dates get big. This hit some weirdness in the date formatting in Chrome, which doesn't seem to like it if the year gets above about 276,000 A.D. I guess that's a reasonable edge case for Chrome to consider low priority. Anyway, I had to make use of the fact that the Gregorian calendar repeats every 400 years to get around this.
It would be nice to add some additional visualization components to this - a dynamic graph showing you move out in time, occasionally almost hitting it big, and all the while displaying the amount spent to date. This would help drive the simple point home, but I think seeing those crazy looking years in this initial version does, too.
