One of the first applications I downloaded from the Sandbox was the "Staff Whereabouts". It's basically an in-out board to see the status of a workgroup. We actually got the application to replace an AS/400 based! signout application. I have commented at the sandbox that I have reworked the ui and have web-enabled the application. I actually web-enabled it a while back. We only have one or two people that may use it on the web, so not much time was invested in it (it's mostly if you need to signout in a pinch). But about a month ago I completed changed the colors of the ui. It could stand for a complete overhaul, so forgive me if it still looks like a Notes application. :)
Here's what it looks like now:
If anyone's interested, post a comment. I don't want to link directly from here since it's not really my application.
