A "Miraculous" Apollo App

Whenever I think about retirement, etc., I wind up in Excel to do simple compound interest calculations because I love visualizing the "miracle" of compound interest.
Today, during lunch, I whipped up an Apollo app that lets me keep track of investments. I can enter an investment, rate of return, and annual contribution, and it shows value over time for each on a chart along with a total portfolio value. All data is saved to the filesystem, so it's right where I left it when I come back.
If you want to play with it, it's available for download at http://www.firemoss.com/demos/apollo/compoundInterest/compoundInterest.zip.

Very slick. I usually end up estimating because I don't have a decent tool for it. Nice quick way of accessing that data! One note though -- could you perhaps increase the maximum time a little father out? Maybe 50 years or so? Maybe even more for the fun of seeing a time when I'll actually have money. :p
