I talked with Laura a little last night and after seeing the MIT Random Hall Bathroom Server and Laundry Server (scary) linked from mattcain.com, I decided to make up a little script to display when the webcams on this page were last changed (you can see it over in the right column). It’s a really simple script, and I think you can use it for any file, not just images.
I decided to go open-source with it. If you’d like to use it on your blog or web page, you can download the source below.
