I'm constantly reminded how much programming talent is out there on the web, and it amazes me how much of it is freely given. The example that made me think about this is the overLIB library, a very nice popup script written by Erik Bosrup and Robert Boughner. You can see what I did with it here. Just click on one of the titles to see the nifty popup window. If you can think of a way to use this neat tool on your site, let us know!
