I built a little java program when I was bored a while ago. I have been periodically updating it and handing it out to some friends, and in a bout of extreme boredom today, I converted it to an applet and posted it. You can find the applet here:

I have very little skill when it comes to webpages, so I apologize for that. If you want to post it somewhere else, feel free, just let me know.

Sorry for the double post, internet issues...

Closed, double post, etc.
