My suggestion is to take something you use now that's not a perl program and see if you can do better. Or fix what you think is missing. And yes I know Perl isn't always the best language for everything, but I think you're expanding your horizions and honing your skills by doing that. YMMV.

One I'm working on right now is a Stock ticker using Perl/Tk and eventually I want to use the Win32::GUI. I'm not particularly strong in Tk, so I figured it was a good opportunity to play with it, and I've never used the Win32::GUI, so even better.

The reason I'm doing this is that I used to use a freeware program that did the same thing, but for some reason it doesn't work anymore, and the author's web page is down. So after looking at a few freeware solutions, I rolled up my sleeves and decided to do it myself.

Currently I've got it refreshing cleanly, so now it's off to a more elegant interface and a few pop up windows for looking up symbol names and adding/deleting stocks.

With any luck, it's going to be in CUFP in a week or so. :)
