Konfabulator
Not being a Mac person these days, I’ve watched the development of the various flavors of OS X from the sidelines. One of the more recent additions to the OS is widgets. These are small gadgets that sit on the desktop and do something simple but useful. Examples might be a clock, news ticker, or battery gauge.
Now Windows users can get in on the action, and I have to say these things are mighty fun. Konfabulator has dozens of widgets written for it, and I’m finding all kinds of useful devices. I have a nice analog clock in the lower right corner of my screen. What makes it unique is that I have its opacity set to 50% and it’s always on top, so I can see what time it is no matter what else is open, but I can also see the windows under it. The best part is it’s completely transparent to the cursor, so I can click on the window under the clock as if the clock wasn’t there.
