The OSU (Oregon State University) webcam widget for OS X was developed in May of 2007 for students and alumni of Oregon State to monitor the webcams from their desktops.
The webcam widget (Oregon State University widget .zip) lets you select from a list of webcams across the OSU campus and specify an update time for the images or, if available, set to a live stream. There is also a version for the University of Oregon (University of Oregon widget .zip). The widget is no longer supported, however a web app has been made available at http://www.happymaau.com/OSUWebcams. The site does support mobile devices, so it’s a great way to get view the cameras from your phone or other mobile device.
